DIY 3D Printed Ice Cream Machine

thingiverse

A simple 3D printed ice cream machine. No 3D printed parts come into direct contact with the ice cream. Works by turning a jar resting on 2 bearings which churns the ice cream. The whole machine stays inside a freezer during the whole process in order to freeze the ice cream. Print at 99% if needed, as tolerances are pretty tight.
