Counting Coin Trays by SuperAmi Oct 11, 2011

Description

This is just a quick coin tray that I made. I started with a minimal one, but it didn't print well, I then moved on to a printable straight tray designed for one roll of coins. Then I created this offset one. Each of the three designs are in the scad, and each one corresponds to one roll of coins.

The STL files are for 2€, 1€, 0.50€, 0.20€ and 0.10€ coins respectively. They are also adjusted to the tolerances of my Thingomatic Mk6. The scad has a parametric cointray() module, that can easily be adjusted to any size coin, as well as any number of coins per counting offset, or to a different printing tolerance.

The counting tray is easy to load and unload, and should be useful to anyone who needs to count small amounts of change.

I had originally planned on printing them all on one tray, but that is larger than will fit in my printing bed.

That is great. I have been trying to think of something I could do to count coins and this far exceeds anything I could have come up with. It is simple, printable, and so inventive. This is rocking, because I can make these and give them to friends. They then can instantly understand what a 3-D printer can do.
