We made this model to add support to the curtain. It's functional and the correct height. I added the blender model if you want to edit the shape and size and shape and size of the hole for the screw. 

We're considering printing animal faces and adding to the front, hence why I left the front so tall. 

TI's the cheap 3$ curtain rod from Target. The curtains were a bit too heavy, hence the need for an extra support. Made it thick so it would take all the weight and extra. It's a bit ugly but it's functional!
