Yet another wire hanger...

This is designed to temporarily hold wires. The sides should be flexible, so the wire can both slip in and out with a small amount of force. The opening is tapered to help make this easy.

This clip has less bottom surface area than some of the other wire hangers, and so might not hold to the adhesive as well. This might limit the amount of weight it can support.

Print with a flexible plastic like ABS. (PLA is almost certainly too brittle.)

Carefully sand the bottom smooth for best contact with the adhesive.

Attach double sided sticky tape.

Place on a surface where your wires need support...
