Print your own pneumatic screwdriver! It is a small, lightweight and powerful tool for screwing and un-screwing bolts, wood screws etc. The bit holder can be made magnetic by inserting a Ø 8 x 5 mm magnet mid-print, although clamps can also be used.

The screwdriver can be equipped with the R-38 or R-52 pneumatic rotary engine (R-52 is recommended). The gear ratio is approx. 10:1 (more precisely: 36/14 * 40/10 = 72/7).
