Embroidery hoop

Improved, 2.0 version here https://www.thingiverse.com/thing:4489960

This is a simple embroidery hoop I designed to learn 3D designed. The thread on the screw and in the hole have a small pitch (distance between the "teeth" of the thread) so you should print this in 0.15 mm resolution for best results, although I haven't tried anything coarser. So far it's worked for holding thin and thick fabric but this is the first version and I might change it as we use it.

I included a "thread test" file that you can print to test the tread. If this doesn't work the full hoop won't either.
