LEGO Dots / Round Studs Counting Tray
Based on a pharmacy 'Triangular Pill Counting Tray', this is graduated specifically for counting LEGO dots & round studs. The numbers on the side indicate how many dots you have if you fill that row. In the multicolor version, there are also markings to indicate exactly 100 and 200 pieces. This can also be used to count any round objects, you would just follow the row count chart. The open area in the top-left corner allows you to pour out the contents when you are finished counting.
I have included two STLs for the multi-color print, one for the tray, and one for all the text. You should be able to open them both together and they should automatically line up. I have also included a single color tray.
Printed size in 170mm x 190 mm, so should fit on most printers. Printed using 0.4 nozzle with 0.2 layer height. No supports needed.
