About this 3D model

I made this because according to my lease, i am not allowed to drill into the tiles in the bathroom. And every tension-fit rod i have tried, has failed eventually. So i wanted to make something that could hang from the ceiling. I decided to make it adjustable because i was going to have to split it into two parts anyway, since i needed about 300mm and i only have the basic 235x235. added two printfiles. The shorter one is light-weight, will hold its end of a shower curtain no problem. The longer one is 6 perimeters and will probably hold several shower curtains xD
