Got tired of bashing my head on this corner in my basement. Just modeled up a corner protector with screw holes and without screwholes. This can be used to on the corner of a box too to lift it off the ground or protect the bottom. Prints fast. No supports needed. Can also be used on the corners of tables and things of that nature to keep kids from whacking their heads on the corners. If you don't use the version with screw holes you can just use double stick tape.
