Summary

Video about this servo: https://youtu.be/bRsKDwj_J3o

This is my project of a Big 3D Printed 81:1 Herringobne Gearbox that is designed to work like a servo. Gear ratio between gears is 3:1 and there are 4 levels of gears which gives a reduction of 81 to 1. To power this servo I used an electric motor from my skateboard and together with this gearbox it really is strong . On my tests I achieved about 15Nm of torque , but it should be able to easily do much more.Keep in mind that this servo has some backlash and isn't very precise but it is a great proof that you can make servo out of anything. Watch my video to learn more.

Here I am giving you all the files, including .step and .f3d so feel free to remix and use them as you want.

Parts to print:

1x Top Gear
3x Gear 39/13t
1x Motor Gear
1x Keyway
1x Bottom
1x Top
1x Case
1x Servo Arm
1x Potentiometer Gear

Parts list:

2x 8mm steel shaft 120mm long
1x Bearing 6908
3x Bearing 608
5x Bearing 688
4x Short M4 screws to mount the motor
6x Long M5 screws and nuts fto mount the servo arm
Some additional screws to hold the whole case together

1x Brushless Motor in my case Flipsky 6374 (You can use any motor you want but first check if it will fit correctly)
1x Vesc
1x 10S battery (you can use any battery that works with your motor)

Also to make it work like a servo you need:

1x Arduino
1x Rotary Potentiometer
1x RC transmitter and receiver or a servo tester

All the arduino codes that I used in my video can be downloaded as a zip file

If you have any questions feel free to ask me here, or on my Youtube channel or via email [email protected] . I am always glad to help somebody
