I ordered a couple IKEA Skådis pegboards today and they both came with corner damage. I figured this is probably the level I can expect from IKEA QA, so it's not worth doing a time consuming trade in to get boards in a similar state.
So I whipped up a quick design for corner bumpers to cover the damaged corners and protect the rest. My goal was to make something that looked like it could have been sold with the boards the begin with.
