Hello Folks! Welcome to Our Blog.

My brother and his friend run their own Dungeons and Dragons campaigns, I asked them both what aspect of their game could be improved on, since neither wanted to admit to their own faults, they came up with the idea that people don't try and role-play much to earn inspiration. Inspiration in DnD is basically a tick box that allows your character to make someone or themselves re-roll and attack or ability check, this can literally mean the difference between life and death of characters.

They only give inspiration when a person makes smart decisions or role-plays their character exceptionally. I asked a few of their players why they don't try hard enough, and one idea I got out of it was that it was just a box they would tick and un-tick, and that feels boring.

So I went back to the Dungeon Masters and asked if they wanted me to design them some Inspiration tokens.

They both agreed. You may note that the picture of the tokens are World of Warcraft related, and not DnD. That's because I already designed the DnD ones before deciding to make this Instructable. Internet you'll need to find inspiration for details. Since I designed mine for my brother, I was able to ask what he wanted.

He wanted something relevant to DnD and small enough that he could play with them in his hand while the players are doing their thing to encourage them to think as their characters would. Since I had a ruler on hand. I figured 3 cm would work alright. But, since were going for details here, we're going to work in millimetres. This step is fairly straight forward, start a 2D sketch and make a circle in the center, make it as big as you want in diameter, as stated above, I went for 30 mm.

From there, simply finish the 2D sketch and extrude it to how tall you want it. I decided to make the coin in two sides and I'll later attach them together. I extruded both sides 2 mm so the solid part of the coin will be 4 mm thick. Because if you make this in two parts like i have. You can cut out a circle from the underside at the size of a metal washer or something heavy and that will fit. Then just put it inside before you attach the two halves together. Alternatively, if you make this in one piece, you can make the empty chamber inside the coin, then simply pause the 3D print once it passes the height of the washer, and slot it in, then resume the print.

Another idea is to make a sleeve that the sides and washer would fit in then stick them all together. I don't admit to be one. So the next step is to go online or wherever, and find a nice picture you want on a coin. Start a sketch on the face of the coin. A lot of modelling programs will allow you to insert a picture into it, so just throw it in there and re-scale it to the appropriate size. Put it where you want it, I left a good amount on the outside of the coin so I could later add a boarder stripe around the coin.

Since we're smart cookies we're going to notice that the image is identical on the two halves. This is vital because it means we only have to do half of the work. To start with, place a single line down the center of the image, then we're going to use the function called 'Spline'. This is a curve generator that makes curved lines based on where you click, for large areas you don't have to use as many points, but for tight corners you'll want to put more in.

Once you've done that or just given up on most of it. Were going to use the 'Mirror' function. Highlight the image lines you've so expertly traced, and select that straight line we made earlier as the mirror line. Click apply and pretend you've put in twice as much effort. Remember to delete the center line, for no other reason than we don't need it. Up next I'm going to introduce you to your new best friend.

We call him 'Sketch Doctor'.This week, HENSOLDT announced that using a newly-developed dielectric polymer and conductive inks from Nano Dimension, the company has successfully assembled the first layer printed circuit board PCB mounting electronic components on both sides of the board.

This the first time that a 3D-printed board has been able to stand up to the tough soldering process that dual-sided boards require. But, until a manufacturer produces such a board, the product is just a dream that only exists in the memory cells of a simulator.

A complex board can be generated at a relatively low expense—and in a day, not weeks. With the fast turnaround enabled by additive manufacturing, an up-to-the-minute board is quickly made available.

Additionally, for low-run products, using PC printing can serve the whole product cycle, and engineering changes can be easily accommodated at greatly reduced time and expense for fast-evolving devices. Finally, additive manufacturing can be a great aid in impedance controlwhich requires precise fabrication of PCB interconnects.

As described by Nano Dimensions, employing 3D printing for PCBs fabrication allows designers to go beyond the standard trace geometries available with standard planar manufacturing processes, ensuring tight impedance control.

This additive manufacturing platform integrates an inkjet deposition printer with its own nano-inks and 3D software.

The unit prints electronic circuits such as antennas, capacitors, PCBs, and sensors. AgCite Nanoparticle Silver Ink. Silver particles of 10 to nanometers in size are controlled for shape and particle dispersion, enabling the ink to be optimized for applications such as RFID and OLED components while maintaining excellent conductivity, adhesion, and flexibility.

Dielectric Nanoparticle Polymer Ink. Polymer inks are designed to complement the conductive silver inks and can accommodate width tolerances down to hundreds of microns. To live up to the challenges of multilayer PCB printing, important properties in adhesion, thermal dissipation, and flammability have been designed in. To have high-density components quickly available with reduced effort by means of 3D printing gives us a competitive edge in the development process of such high-end electronic systems.

While many observers mistakenly tout 3D manufacturing as a way to mass manufacture simple products, the real future of the technology seems to lie in prototyping and short-run devices.

Like my Apple Coin Bank design, this model was designed to teach the grandkids to save money, but includes an additional feature; if they change their minds and wish to make an "early" savings withdrawal, well, I didn't shown them how to open the bank. Featuring dovetail fixed joinery, and a sliding dovetail top, the trick to opening the box is, well, you'll figure it out eventually The locking mechanism is based on the German designed "Radbox" "rad" in German translates to "wheel" in English that incorporates two mirror image slotted wheels in an ingenious manner to keep the box closed.

While the design of my locking mechanism is more "cam" shaped than "wheel" shaped, the principle of operation is the same. And as in the original design, the locking mechanism remains hidden from view, even when the box is opened.

I could not locate the original designer for this mechanism, so if anyone has their name I would be grateful for it in order to give them proper credit for their ingenious design. There are no batteries, power supplies, motors, springs, computers, wiring or any other hardware required to build this model, just 3D printed parts, which is one of the many reasons I truly enjoyed designing, printing, assembling and testing Simple Secret Box II: Coin Bank.

As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make mistakes in plenty. Designed using Autodesk Fusionsliced using Cura 3. Prior to assembly, test fit and trim, file, sand, etc. Carefully file all edges that contacted the build plate, especially in and around the dovetail joinery, to make absolutely sure that all build plate "ooze" is removed and that all edges are smooth. I used small jewelers files and plenty of patience to perform this step.

Start the assembly process with "Side, Left. Orient these components as indicated in the photograph then press them together. Next, using the "End, Lock. The cams must pivot easily on the axle. While aligning the end lock axle with the hole in the divider, press this assembly onto the end of the sides and divider assembly as shown. Rotate both cam 1 and cam 2 such that the flat sides of each cam are parallel with the divider then hold in place with a business card.

Next, slide "Top With Slot. With the box closed, you, your family, your friends, etc.

I remember when Thingiverse first launched, there were all sorts of awesome looking 3D printable design made available. I was like a kid in a candy shop, sorting through all the eye candy that was suddenly available for me to print out at home. As time has gone by, we are beginning to see the creation and open sourcing of 3D printable designs which are not just neat to look at, but ones which serve useful purposes in everyday life.

Luckily the internet is filled with creative minds, those looking to 3D print objects which can provide benefit to our everyday lives. The Auto Coin Sorter is available to download on Thingiverse, totally free of charge. While this can printed on virtually any 3D printer with a large enough build volume, Chen printed his on an Ultimaker 2 using Cura Software.

The complete recommended settings may be found in the instructions posted by Chen on Thingiverse. This is just another great example of a design which could be quite useful to those needing to make their lives a bit more efficient. What do you think about the Coin Sorter?

Well, it is and I can assure you it works just fine. I would not use it as a main key, but it is great to print a few spare keys to your room, office or house. Save your key on a usb stick or cloud drive and print it anywhere! I only have 1 key to my office so I decided to test out a 3D Printed spare key.

Like I said, it is perfectly fine for a spare key. Download OpenScad here for your operating system. If you've never used or heard of OpenScad before, it is a great way to create customizable parametric models.

This means that I could give an OpenScad model to someone with zero modeling experience and that can modify it just by changing a few numbers. These models were created by Nirav Patel. Open the file in OpenScad and change the last line of the code by entering in the key code of the lock. Your key may have the key code written on the side, but if not you can measure the key and compare the numbers here. Compile the program and then export the file to an stl that you can print.

Threw a plastic one in my glove box of each car. I reverse engineered my numbers from my metal key. Reply 5 years ago on Introduction. Might want to remove the measurements and measurable image. On an instrucable about 3d printing a key, you basically just gave the internet a copy of your key.

If someone copies my key from a picture and they somehow find the exact lock that the key opens, they deserve my stuff. I think it is stupid when I see someone blurring their keys on the internet. If someone wants to break in, they will break in. Your locks are not safe and if they are, then the key can't be copied from a picture anyway. Reply 2 years ago. Actually I copied my house key with a picture tool some time but didn't need to install anything just used the windows 10 3d paint and builder 3d.

Keys can be copied from photos. I know, regular keys are not very hard to copy. I was heavy into lockpicking and could open most front doors in a few minutes without a key. You can not copy a medeco key even if you had it right in front of you. A locksmith will not even attempt to make a copy of a medeco key without the original card with the code on it. Good luck. Have to get into the building, past the alarms first. Much easier to throw a rock though the window.Hey you guys!

My last instructable was making the Goonies treasure map. The next piece of the puzzle has to be the doubloon that goes with it, since it is drawn on the map and guides Mikey to the restaurant where the hunt for the rich stuff really begins.

First, let's over-analyze the movie prop! For a start, the Goonies doubloon is not really a doubloon. Doubloons were small, gold, and worth 32 reals, i. By contrast, the the Goonies doubloon is enormous and clearly not made of gold. It's not even based on a Spanish coin. Did the prop maker choose these designs just because they looked cool? Where they sculpted from scratch or adapted from coin moulds from some earlier production?

We may never know. The makers of the Goonies would have been the right age to have visited Disneyland as kids during the s I strongly suspect there is a link here! The next thing to note is that more than one coin was used for the filming.

There is the one handled by the actors -which seems to match the one pictured in the original fanzine- and another one that was used for the close-up. You can tell they are different by the shape of the holes; I'm guessing they were both cast from the same mould and the holes were filed out later.

Replicas are available online, and slightly different versions pop up from time to time, but I haven't seen anyone document making their own, which surprises me. I therefore looked at lots of pictures and created my own model using Sketchup before 3D printing it. Now you can print your own Goonies doubloon, too! Download the.

STL file and print it using your preferred settings.

3D Print the Goonies Doubloon!

I used PLA and printed it 'fine' 0. The coin is printed in two halves, so after printing you need to glue them back-to-back with superglue or acetone, or whatever you prefer.

At this stage the 3D print is geometrically regular and has all those annoying printing layers. We need to smooth it and deform it to look more like the movie prop.

Lets Make 3D Printable Tokens/coins

If you print with ABS then you may be able to smooth the whole coin with acetone vapour, but I only have PLA which doesn't react that way to acetone.A frequently asked question to coin dealers and collectors is, "How much is a two-headed coin worth? Some people think that a two-headed coin is extremely valuable and they will be able to retire or buy a new car with one. However, nothing could be further from the truth.

These coins are usually crafted by unscrupulous people looking to make novelty coins, props for magician tricks or create a way to swindle people out of their money. The U. Mint does not produce two-headed coins that you find in circulation or buy at flea markets. There have been anecdotal reports of two genuine two-headed quarters that relatives found in the safety deposit box of a deceased San Francisco Mint worker.

Even if these tales from the mint are true, it is a sure thing that no two-headed U. Any two-headed U.

Engineers Create the First Double-Sided 10-Layer PCB Using 3D Printing

That is percent certain. Two-headed coins are made by taking two identical coins of the same denomination and machining them to approximately half the thickness of the original coin. The two halves are then fused together by either welding or soldering the two halves together. This process usually leaves a seam on the edge of the coin where the soldering has oozed out.

The machinist will then grind and polish the edge of the coin in an attempt to hide the seam. Production processes in the U. Mint make it virtually impossible for a two-headed or two-tailed coin to be manufactured by the mint.

The coining presses that are used to produce U. When coin dies are manufactured, the shank of the coin die for the obverse is a different shape than the shank of the coin dies for the reverse. This manufacturing process design makes it virtually impossible for a coin press operator to load two obverse or two reverse dies into the coin press.

Experts are puzzled as to how this can happen, but the professional authenticators at PCGS agree that the coin is a genuine mint product.
