About this 3D model
This is inspired by a freind's coffee mug that was hand sculpted. I set out to do this to work with Meshmixer. Both versions are thin, so it's just a cup. One version has a cylindrical inner bore, the other is about 2 mm thick shell of the shape. I made this into a 30oz cup cozy too. https://www.myminifactory.com/object/3d-print-130347
