Filament guidefor Misumi Extrusion on Mendel Max

This part helped me to solve a lot of problems.
I use my custom filament rod holder http://www.thingiverse.com/thing:1695002 for M8 spool holders http://www.thingiverse.com/thing:545954.
I did a lot of things to prevent my spools from frictionless movement.I needed some friction so filament should not go off.
With this part i don't need this complicated stuff. It makes controllable friction ant guides filament. And simply clicks in place!
