About this 3D model
I have a Patreon page! :) As requested, a version of the Cog Twist Box without the hole in the middle. It looks less cog-like, but I can't deny it's probably a bit more useful for actually storing things in! Oh, and after an interesting comment on the original model, I decided I'd reverse the direction of the twist on this version, to make it more intuitive. If you like the other direction better, or just want to be consistent with the existing one, just mirror the objects in your slicer.
