Set Screw Mount

This is a piece that can be screwed into a shaft to lock it in place. For example if you put one of these on either side of a 3 hole shaft holder, it will stop the shaft from sliding back and forth when turning. The holes are designed for m4 screws, 5 mm long. I have been using normal screws and just digging them into the plastic shaft to secure it, but I'm pretty sure set screws would work fine too.

I uploaded the f3d file and step file in addition to the stl. Feel free to edit it however you like and use it in other projects if it is helpful, please attribute it though : )

Let me know if you have any questions or suggestions!
