Toilet paper holder with aluminium arms

Here is my WC paper roll holder, with rotating arms, sticked with removable double sided tape

It needs, added to the printed parts :

* 2 x 608 bearing (8x20x7mm) - because I like performance, even in the toilet!
* 2x8 mm bolt
* some aluminium rod - 12mm diameter
* double sided tape
* some washers to make movement easier
