Keychain Knife with a button

Описание

The size tolerances are small, so for fine-tuning the parts, it will be useful to remove possible printing artifacts and work a little with a flat needle file in the grooves. It will be better to lightly lubricate the friction points with mineral oil or silicone grease (just do not overdo it, so that the grease does not get on the outside). Before assembling, rub the moving parts and check the tightness of the fit. To put the button in place, you need apply pressure from the back side with force on the ledge the spring.
