I have stabbed myself on occasion by discovering an X-acto knife dropped carelessly in a drawer. When I saw the "Wall mounted xacto holder" by jeremygold, I knew I wanted a pegboard version.Print fairly solid so that the legs are strong. I print my pegboard designs with supports for those upward curving legs. Some people have reported that they can print them without supports. My luck with that has been mixed. The legs are spaced so they'll be intentionally tight. Rock it back and forth gently to get it to seat in the pegboard.
