This is a basic pair of brackets to hold a shower curtain pole or similar,could be used to hold a clothes rail but I would be careful the amount of load put on printed bracket.
As they are made for a shower curtain there will be little weight on them.
They measure 46mm x 49mm and 20mm thick.
The bracket will take up to a 26mm diameter rod, being round a smaller rod will still sit nice in the bottom
The screw holes are 5mm and countersunk up to 8mm head.
They do what I want and if any one else finds them helpful thats a bonus.
I printed two sets as seen in the pictures.
printed in white and natural ABS at 0.4 layer for speed and 60% fill with 4 solid layers.
Came out as I hoped, just run a drill down the holes to clean them up.
