Minimalist Quick Change Toilet Paper Roll Holder

From original author description:

It takes about 5h to print all parts at 60mm/s, uses only around 50g of filament at 20% infill, and can easily be printed on any 3D printer as the shapes are very simple, with no bridges and maximum 45° overhang.

It requires no additional hardware appart from the screws you'll need to attach the base to the wall, it is made to be used with any M4 or M5 screws.

Assembly and installation are very easy:

1. Print all the parts by simply printing the all_in_one.stl file, each part is also available as an independant STL file if you need.
2. Clean them from any defects they might have (imperfections due to stringing or over extrusion, etc).
3. Slide the arms on the base, check that they rotate freely (see bellow what to do if they don't) and secure them by clipping the clips (see exploded view in pictures for assembly details), you might need to apply quite some pressure for that.
4. Screw the base to the wall using whatever holes you need.
5. Clip the cache on the base to hide the screws.
