3D printed Inner Gear Drive | Trampa Holypro | VESC 6 | Overion 130kv | GT2B + Arduino

I am currently working on a 3d printed gear drive for trampa trucks and either trampa gummies or maybe the stickies (90mm). I am so far at the housing gear stage. I will soon create the cut through to mount to trucks. After I do that I will make a thread and post the link here is you guys want to follow the design/build process. I will post the files once I get to a decent position and then I will print and test them. Here is a current render photo. I am thinking of going helix drive.

I pulled the trigger on some steel gears for my eco 10/42. The ratio is now 10/70. Great torque!

Has this ever been completed? I saw there are steel helical gears from @omniesk8 that could be used
