Just transform a glass yogurt can (i used french 'La Laitiere' can) into a geek's coffee cup.
Step 1: 3D Printing
Print parts with 1mm walls and top/bottom, 50% fill and brim.
It worked fine on my graber prusa i3 mk2.
I used PLA.
Step 2: Assembling Parts
Just assemble parts, it's easy.
You may need a little screw driver to push and adjust top and bottom parts around the can.
