This gives you a higher torque - 1. gearstage 15 to 35 teeths --> ratio of 2.33- 2. gearstage 15 to 42 teeths --> ratio of 2.80 ==> ==> You coud use it with DC or Brushless motors with a mount diagonal of 19mm or 16mm or you could add other holes. additional parts:- 1x Motor- 2x M3 or M2 countersunk screws for motor- 2x M3x10mm countersunk screws for case- 1x M2x6mm screw- 2x M2 screws to fix the gears gear- 1x 3mm axis or M3x10mm screw- 2x bear…
