Summary

Picked up this till or cash register if you're not from the UK like me :P, with a missing drawer key someone had wedged the drawer open and it did work, but could not be locked.

Replacement keys can be quite expensive for what they are, so I found a google image of the key and put it through a image to stl converter and cleaned it up, with some trial and error on the dimensions I finally came out with a working key.

The thicker key top works best as it's more durable and feels less like it'll snap

These can be printed in PLA but you may only get a few turns out of them before they break, just don't break it while it's in the lock.

Ideally needs to be printed in PETG or ABS, ABS is a pain to print IMO, I used PETG with no real issues.

I'd recommend a 100% infill with whatever the strongest pattern your slicer has, I used cura with the cubic pattern for added strength

Reccomend printing in PETG or ABS, PLA will work but not for long
