My wife got me a 3D printer for christmas, and as a first project I made a toy-figurine of the character from our game Diabotical https://www.diabotical.com/ and made it into a nice present for my boss and friend.
It was pure joy making this and open the door to the fantastic world being able to 3D-print.
I really wanted to make the figurine fully articulated so there where alot of test prints to see what worked and not, and to figure out tolerances.
