Prusa MK2 spool roller

Here is a small remix between the TUSH - The Ultimate Spool Holder (https://www.thingiverse.com/thing:2047554) and the default Prusa i3 MK2 arm spool holder.

As the original one, the spool holder is composed of four pieces. You will need four 608 bearings for the rolling system and also four M3x30 screws + nuts to well fix the pieces together.

The space between each arms could be easily adjusted to fit any kind of filament spool..
