Enclosed Euro / US dollar coin cell

thingiverse

These days, seeing how things are going we should love our money. I thought that I should give a try to make a coin cell with an enclosed euro or dollar coin. You can write in your name, or anything you want. Simply edit the shapestring and font in the FreeCAD sources. You can even add a hole to use it like a keyring. Or just pay an Euro or dollar with fashion. Or give it as a present or joke. As the coin is totally enclosed, you should print the part till 5.6mm (for the dollar version at 5.2mm ) is reached. then pause the print, insert the coin in the hole, continue printing and let the printer enclose the coin. Recommended print in ABS as 0,2mm layer and a 0.4mm nozzle. Don't use any kind of support!! HINT: Beware, once printed you will have to break the plastic to use the coin in a vending machine. To make it easily breakable you should print it in PLA and throw it to the floor with some strength trying to drop it plain. If printed in PLA you can drop it in hot water (60 to 70ºC) and then bend it with your fingers until the coin pops up. If you have strong hands you can even break it manually, but try to not bend also the coin!!! ;-) HINT 2: At printing time you can also change the filament when the text is starting to print to make it even more cool.

For those of you not having an euro coin at hand, I have uploaded a new model just in case you have an american dollar coin instead. I don't have any dollar coin around, so give me some feedback about this new model confirming it fit well to help people printing this.
