Counting Coin Trays

cults3d

This is a quick coin tray I made. I started with a minimalist design, but it didn't print well, so I moved on to a printable straight tray designed for one roll of coins. Then I created this offset tray. Each of the three designs are in the SCAD file, and each one corresponds to one roll of coins. The STL files are for €2, €1, 50¢, 20¢ and 10¢ coins respectively. They are also adjusted to the tolerances of my Thingomatic Mk6. The SCAD file 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.
