These are lower profile hangers for 3M Command Strips. 3 versions, for mini, small, and medium Command Strips.

I originally had some small wire utensil holders, but the wire hanger pushed pictures out too far. These revised hangers keeps my picture frames closer to the wall. The small and medium protrude 1cm from the wall while the mini sticks out 0.5cm.

I printed these with a Monoprice Select Mini using Warm White eSUN PLA+ 1.75mm filament.
