About this 3D model
This twisted wireframe torus curves in a half-twist around its length, so if you follow the path of a single longitudinal strand... actually, I haven't looked to see what happens there! You know, this might not technically be a Mobius strip in 3D-form, since the 3D equivalent is probably a Klein bottle, but I'm calling this a Mobius torus anyway! As you've probably noticed in the photos, this is a print intended for liquid resin printers (SLA/DLP/LCD), but there's no reason you couldn't scale it up and try it in FDM if you're feeling adventurous! It' won't be as cute, though :D Enjoy!
