A small hanger to attach curtains to a curtain rod.
Adapt the scad file if you need other dimensions. The STL is for curtain rods of 30mm diameter (i.e. those from IKEA ).
I printed 16 from PLA for each 1.4m curtain, you can probably get away with fewer of those hangers. (Print settings: 3perimeters, .35mm nozzle, .2mm layer).
