Shower curtain rod tensioner insert - Modified

This is a slight remix of the shower curtain rod tensioner insert. The end cap is now filled / flat for better printing without any supports.

The rod end is the same, and will have some issues with bridging because of the hole in the design (this could probably be easily fixed by adding a cone or something to the part and removing the hole, which I may do in the future). However, it functions just fine. The original author printed with SLA so this wouldn't be a problem in that application.
