20x20 Test Stacker

thingiverse

I got bored with a stash of 20x20mm test cubes cluttering up the space, so I decided to design a cube that would connect seamlessly to another cube, feature thread printing (M15x1) and print without any overhanging parts thanks to the cone in the center. Each individual cube can be threaded onto another one, allowing for easy stacking. This setup also helps determine if different filaments print close enough together. Please share your multi-colored stacks!
