I needed a place in my workshop to hang my backpack that wasn't my bench vice. This is designed so there are no exposed fasteners and is easy to print. For mounting only one stud would be needed. 

Designed to hang with two #10 screws because that is what I had on hand.

PLA should be perfect for material. 

As of 3/7/23 this project is a WIP and I have not test printed yet.
