I was looking around our house for things to fix, and I saw a lot of places where there was a small hole in the drywall caused by a door handle. I was going to patch all of these with drywall, but I knew it would eventually happen again, even if I adjusted the doorstops. Instead, I decided that it made sense to cover the hole with a plate to armor the wall against the door handle, which would also cover up the hole so that I didn’t have to do a bunch of drywall work.
Looking around for a plate, I found a few that are self-adhesive, which is super handy, but I didn’t want to have to peel it off and risk re-texturing the drywall at some point in the future. I was hoping to find one that I could screw down with drywall anchors, but I couldn’t find exactly what I was looking for, so I made one myself.
You can find the design on Onshape or the STL files Thangs. Use template to mark good locations for screws, and then put #4 screws and drywall anchors into the wall. The screw heights will have to be adjusted so that the plate slides on nice and snug.
