Curtain holder for 19-20mm tube. Just buy tube, cut needed length and use for your curtains.
Contains side stoppers and through holled parts. Constructed to use 4.5mm screws. I created 6mm diameter holes in walls and used 6x30 S K screws for it. 4.5x40 - screw parameters. 6x30 - plastic fitting for wall hall.
Can be printed on 0.4-0.8 nozzle 0.2-0.25 layer.
I used 0.8 nozzle 0.25 layers and it takes around 1.5 hour for each part.
Part have additional holes for 3 mm screws, you can use them to stronger connection and fixation of tubes. but it is not necessary.
