Simple Toilet Paper Holder (with shelf for phone)
It is mounted to the wall with two screws M3. Depending on your preferences you can use diffrent mounting method.
Part consists of two models. Hand closer should go in tightly, there is no need of taking it out while changing toilet paper. You can glue the hand closer for tight fit. Personally for me it stays tight fitting and no need for glue.
Shelf has little raised corners, so that your phone wont fell down durning the ritual :D
It is a simple model and really useful one. Part is modeled that you can print it without supports. Although if you feel your printer cant do it you can use some. I have printed the model without supports and everything turned out fine.
