Basic curtain rod bracket - min 11mm or 13.1mm inner diameter rod

This item was initially designed to replace a broken roller blind bracket.

That particular roller blind had cogged inner recess (which the 11mm version matches).

But these can be used in general with hollow metal rods, so have added another size (for minimum 13mm inner diameter curtain rods).

And I also added screw holes, for general use.

It prints in place, without supports, as-is when the model is opened.

Notes:

My curtain was fairly light, so I used 15% infill and two walls. You should be able to print at 100% infill, if you want more strength.
