Hi there !
Are you tired of spilling your expresso on your desk ? Well boy do i have the solution for you !
This is a very simple expresso cup holder, its made for 12cl cups, because of the shape of the holder, it can probably take bigger cups too, but they might stick out too far.
PLA works fine, if your coffe is super hot, you might want to print it out of PETG or ASA.
