Wall mounted toilet paper roll holder with shelf.

For your phone on the throne. As one does. Holds the wipe scroll after you scroll.   This modern plumbing adjacent device and telecommunications accessory is an excellent example of poop deck engineering.

The model is in 5 pieces on two build plates.  I wanted mine to be sturdy and look pretty so I it takes many hours to print with my profile.   It has tabs and locating pins to ensure all the parts fit together flush and square.  I used super glue on the parts (and a #8 sheetmetal screw to hold the wall plate to the roll hook), and I let them set overnight with a dozen rubber bands holding all the pieces together.   I also used 2" #8 screws to mount it to the wall.  Use buttonhead or cap screws unless you like watching plastic crack.  And don't overtighten this doesn't need to hold up my 300kg of sparking unicorn rainbow filament, it only holds a featherweight roll of Cornhulio's finest.

Lastly,  please give me a boost, a photo of your print, and a comment. Don't show your leg and dropped trousers in the background of the photo, please.  Your mom already showed me that photo and I am trying to forget it.
