Nail Hook

thingiverse

This is a versatile wall anchor designed to secure itself firmly to hard concrete walls without creating unsightly holes. To mount it effectively, you'll need a 3mm masonry drill bit, which should only be inserted about 5mm into the wall at a time. Once the hook is in place, drive a 12mm long nail, measuring just 1mm in thickness, carefully through both the hook hole and the wall hole using a hammer and punch tool to ensure a snug fit.
