Confuse your groggy morning self with this mind bending squircle mug. It's an ambiguous cylinder that you can drink out of (provided you print it in a water tight, food safe material).

Support material required

I just printed this as a model using PLA but it still holds water. If you want a food safe mug you may want to coat this in an epoxy like XTC-3D or get it printed in ceramic (pricey!). It's also just neat as a prop!
