I have several of these PCL705 Ryobi vacuums around my house and garage. The way Ryobi wants you to wall mount them is a single screw in the wall and the slot on the backside of the vacuum.

Ive had problems with the screw pulling out of drywall and getting loose, so I designed this fast and easy to print bracket. I would say PETG would be preferred but PLA should be fine. Add support under the hook area. Also included the .f3d file if you'd like to make any improvements to the design.
