Simple and effective curtain rod bracket. I think it looks quite nice too :)

Print settings:

• Print laying down so that the layer lines are oriented for strength.
• 16mm layer height or lower
• 8 perimiters (basically solid) if you want it to last.
•  

I have some ideas for further development of the design:

• Some slight adjustments to the aesthetics.
• Separate mounting plate so that you can easily hide the screws.
• Replaceable “load limiting” mounts between the mounting plate and bracket, so that if you for instance step on the curtain, you won't pull out the drywall screws, but instead just break some small replaceable pieces of plastic. 

• Load testing and design improvement based on results.

   

If you have any requests for design changes, or another curtain bracket design entirely, let me know and I'll see what I can do.
