Curtain holder for radiator

A thing to easily drop the curtain over (and back) radiator to let the heat out to the room and not behind a curtain.

Clips to radiators with 40mm long gaps. It is designed to be used with White Smooth Pencil Round Architrave Flat - Length 5m x Width 95mm from Eurocell

Print on the side with supports. Mirror the end bit in a slicer to get both ends. Files marked (easy print) aren't as round if you struggle to print round bits nicely  in PETG (I did)
