Toilet paper shelf (modular, 3 or 5 rolls in a row)

The model is pretty straightforward - print either 3 interlocking parts or all 5, which gives you 15 or 6 rolls of storage accordingly. Fits for rolls up to 130mm in diameter and 100 mm in height (normal EU size), Fusion 360 file provided, so you can change these parameters.

Fix with screws or double-sided tape. 

Almost any filament or print profile will work.
