Gearless 90-60-45-30 Degree Torque Transfer Tool (Angle Drive)

I had a project made, and I realised after that project, it was really hard to print gears and correspond them. When I was searching for a model for a gearless power transfer product, I came across this method, but I couldn't find an STL file, so I decided to model it. I'll be honest, due to the flex of the parts, it is not efficient as the gears, but I'm sure some of you may find a purpose for it.

There are two kinds of shafts in every angle version. One is the centre rod with pin cutouts; the other is the torque-bearing rod. 

IMPORTANT: PLEASE GREASE THE PARTS

Here is a stiffer version I made with shorter hub and shafts:

For each angle, only the shafts change.

To print;

• 2x Hub

• 2x Pin Couples

• 4x Rotating Shafts (Corresponding angle)

• 1x Centre Shaft (Corresponding angle)

Please leave your makes and reviews so I can revise it.

Feel free to contact me if you have any ideas you'd like to create and donate to the community.

Thank you in advance.
