I wasn't happy with the toilet paper holders that I've seen out there. So I made my own. This is a modular design so you can print as many middle sections as you want to extend as high as you want. Each piece has it's own little shelf, so you just print, screw to the wall and place your toilet paper. The tolerances are pretty tight at 0.1mm, which printed just find on the bambu. Uses standard drywall screws to screw to the wall.
The height of the extension piece is 165mm
