Fix for key head

thingiverse

A buddy of mine recently asked me if I could fix the head of her bike key using my 3D printer, so I decided to give it a shot. I created a new handle design on Onshape after snapping a photo of the key shaft and generated the G-code with Slic3r. Using an online G-code viewer, I figured out where to place the key shaft in the code to incorporate it into the new head without colliding with the hot-end. After that line, I added the following commands: G! X0 Y0 G4 S60 These commands move the printer's head back to the bed's XY origin and pause everything for 60 seconds. The printing process went exactly as planned. About two-thirds of the way through, the hot-end moved away from the part, so I added the key shaft and waited 60 seconds before the printer started again with the remaining print. I'm really happy with the result, which turned out to be surprisingly stiff and functional.
