Inclined Spool Holder 22.5°

Hello! Here is my new spool holder which is inclined at 22.5 °.
I designed it because my old setup (inclined paper towel holder) did not work
with the new EconoFil PLA rolls purchased (1 kg for 16 $ CAN - filaments.ca) Amazing PLA By The Way!

This Spool Holder is simple but it takes a lot of material but does not require bearings or screws or assembly.
I tested it with a brand new/barely empty spool and the Spool Holder does'nt move
but I'm going to put small pieces of rubber underneat
