I looked at other models people had made to hold air tools. I wanted one that held the tools at and angle so they don't have a chance to fall out of the holder, so I designed this. It looks small and like it won't take a lot of weight, but printed with PLA+ it has been able to handle my giant heavy Ingersoll Rand impact gun fine for a year now. Mounts on whatever you desired surface with a regular drywall or deck screw. Print them solid for best results!
