Heavy-Duty Knob-Clamp Wall Mount

As part of an ongoing home organization process, I needed a heavy-duty wall mount to secure an aluminum ramp to plywood mounted on my garage wall for storage.  Design criteria included easy on-off mounting and an attractive appearance.  The design utilizes commonly available hardware and its strength is not dependent on the filament-printed parts, as they serve as carriers for the load-bearing metal hardware.

Each mount requires the following hardware:

Tips:

• Use the printed mounting base as a template for drilling the three screw holes in the fender washer.

• I printed all the parts with PETG-CF, however most of the load is carried by the metal hardware, so regular PETG would suffice.

• Use the length of 3/8-16 bolt that suits your application.

• The optional spacer can be threaded on and adjusted to any distance along along the 3/8" bolt to serve as a stand-off if needed for the application.

While I am confident that this 3D-printed design will work for my purposes, please understand  that it is experimental and hasn’t been professionally tested or certified.

I can’t guarantee safety or performance and I’m not responsible for any damage, injury, or issues that may result. Please use good judgment and, if you need something for a critical load-bearing purpose, consult a qualified engineer.
