Powerful 3D Printed Brushless Motor Servo

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 basementcreationsemail@gmail.com . I am always glad to help somebody
