Hinge support for curtain rod

The entrance door or my house is too close to the celling so it didn't allow me to use systems with hooks over the door even as thin as 2mm.
Can't drill in the door either as it's a rental house and I was afraid double sided tape woulnd't be enough to hold more than a very thin transparent curtain.
I saw a rod with a hinge like that in a hardware store but it was too exepensive to my liking.

I had an extensible 10mm rod lying around so I did this design around it.
Completed it with a small adhesive hook on the other side so it's following the door as I open/close it.

Print it like the screenshot shows to make it more solid.

Let me know how it works for you. I'd be happy to know.
