About this 3D model

I have my filament spool mounted above and behind the machine so the filament can be easily fed into the extruder, however there was one problem, the filament would rub against the 8mm threaded rod when the extruder head (x-axis) moved back and forth.So I thought, why not use a left over piece of 8mm smooth bar to fix it.And to easily mount this I needed some quick snap in brackets, so here they are!
