A simple cable hanger design derived from the excellent work by StinkyWeezle on Thingiverse.

Some minor quality of life changes made, including dimples to resist “twisting” when installed on wood or particleboard desks, and a larger clearance hole to suit M4 screws and a correspondingly deeper counterbore.

Easily printed without supports or brims from PLA - I recommend printing these with the flat face on the bed.

Fast to print and very secure!
