Descripción
Precise screwdriver sharpening tool. Often used by watchmakers, it will take care of proper angle of screwdriver.
Use 608 ball bearings (same one as for fidget spinners and skateboards), and M3 machine screw (hole is 2.8mm) and screw it into plastic. Print flat, glue together and then hammer ball bearings onto places.
