Awesome -- my daughter loves the the colored ones. I'll have to ask if she needs any extras. 
I was just thinking about either searching for or designing one of these tonight! Needed something small, simple, and useful to print out to test out my Galomb plastic injection machine. Too funny!

Instructions

Print out many copies of the STL file, and make a huge bundle of different constructions. I was reminded of these when I saw the lockable poker chips. These are essentially the same thing, but a bit smaller.

A 4-piece model is also provided, which doubles as a bed-level calibration device. The shapes should be 25mm diameter, 2mm thickness.

My great uncle brought a multicoloured set of about 100 of these back with him from Taiwan about 20 years ago. I can now finally make some to replace the ones that we've lost over the years.

The part profile expects an extruder overprint of 0.25mm for a good friction hold (I call this "extrude width"). The source file has now been changed to a parametric openSCAD format to allow customisation of pretty much everything.
