Do you need a friction torque limiting coupling for only $10? How do you bring the cost down from $150 to $10?

Simple. Design a custom torque limiting coupling!

In this video we will design a custom torque limiting coupler from scratch.

First, we will review the high torque motor the torque limiter will need to protect. Then, we will select the standard hardware and design custom 3D printed parts around the hardware. Finally, we will test the coupling, make design updates, and measure the torque that the coupling slips at.

So will the $10 custom torque limiting coupling work?
