Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This is a 3D-Printable "Useless Machine". Hit the switch, and the useless machine uses a tiny arm to switch itself back off. These are popular gag gifts, and make for a great desk toy!
You can print this one yourself, and the parts are really cheap. Check out the instructions for a parts list and assembly steps.
