###[More Projects on our Youtube Channel](https://www.youtube.com/jtronicsTV?sub_confirmation=1) to get notice of a New Upload! https://www.youtube.com/jtronicsTV?sub_confirmation=1 how to assemble the gearbox: https://youtu.be/W3gJ8Fz_9Tw This is a gearbox for various motors. I designed the gearbox to test how durable 3D printed gears are. So the test is a part of a bigger project that I am working on. Maybe someone will find this project usefull. It's Easy to print and assemble and the gearbox runs really good. The gearbox has a reduction of about 1:6.5. 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 bearing 623zz 3x10x4mm - 1x bearing MR63zz 3x6x2.5mm Website: http://www.jtronics.de/ Instagram: https://www.instagram.com/jtronics.de/ youtube: https://www.youtube.com/jtronicsTV Facebook: https://www.facebook.com/jtronics.de/ Thingiverse: https://www.thingiverse.com/jtronics/designs Cults3d: https://cults3d.com/en/users/jtronics
