Parametric Coin Storage Tube(s) + Cap
by newq, published
The STL file are for 2 tubes that can hold 25 "1 Euro" coins each.
If you need them for other denominations just change the configuration in the OpenSCAD files.
I hope these are useful for you.
For you convenience I activated the MakerBot Customizer thingy. Just click the "Open in Customizer" Button. :)
UPDATE 1: Thanks to additions from kitwallace you can now choose for which coin you want to print the storage tubes.
I added Euro, US and Canadian coins. Please let me know if there is demand for other currencies.
UPDATE 2: There was a typo with the size of 2 Euro coins (, instead of .). It is fixed now.

So I added Mexican Pesos (not all variations though) to the list, I'll add a picture after I actually print these and put some coins in.
Thanks again newq!
Oh sorry, I totally forgot to mention that! Also I mixed something up. It's the coin_tube_1_3_1.scad file you will need to edit, not the .stl.
Basically it's just a textfile (think html or sourcecode from a programming language), so you can use your favorite text editor - even notepad or textedit.
If you want to learn more about the description language that is used you can have a look at http://www.openscad.org/ and look at the tutorials and documentation there. But I'm pretty sure you can make sense of what you need to edit in the file to add new coins. :)

The OpenSCAD file generates the tube and a fitting cap to close the tube.
To create the tubes you want, just change the configuration and export new STLs.
You need to setup:
* coin diameter
* coin height
* number of coins you want to store in one tube
* the number of tubes you want
* if you want a fitting cap generated or not
The defaults are for 2 tubes that hold 25 "1 Euro" coins + cap.
For your convenience (and mine) you will find the settings for all Euro and Euro Cent coins inside the OpenSCAD file.
I print them at 0.3mm layer height, 3 shells and 20% fill in on my Solidoodle 2. When the bottom layers are finished I turn down the speed a bit so they come out nicer.
