I built this with ABS and it looks and works great. The hex hole in the maingear fits a Phillips head screwdriver attachment for a drill. Pretty interesting this makes a very unique and unusual screwdriver handle which ratchets both ways (screwing in and screws out). Just an adaptation of your cool skewed planatory gear set. i cansend you a video if you like. fvfly
