Instructions
Print three. Have a small amount of fun fitting them together.
Actually, I designed this as a 1x1x3 cm test part to test for shrinkage.
It works well as is, but you might want to build it bigger if you want a real toy.
Also, this has no tolerances at all (since it was meant as a calibration part), and probably should have the middle section stretched a bit to make it fit. (I'll upload a fixed version too when I have time.)
