Spill-Proof, Shatter-Proof, Insulated Glass Coffee Mug

Spill-prone at the office? Looking for a fun 3D-printing conversation piece that also keeps your coffee warm? Look no further. This spill-proof 8 oz. coffee mug has all the ergonomics of a traditional mug, but won't shatter if dropped, is well-insulated, and comes with a lid to keep your coffee warm and in your mug. No more spills on the way back to your desk!

Hand-washing recommended. In fact, I'm pretty sure PLA will melt in most dishwashers, so don't put it in there.
