Cetus3D spool arm

I printed this awesome integrated spool holder (https://www.thingiverse.com/thing:2805075) and noticed a rubbing noise which was from the spool rubbing the holder due to misalignment. So I created this tiny add on which lines the filament up so no more rub!

It attaches using one of the supplied 90 degree metal brackets. It doesn’t really need a screw but i designed it to use an m3 and nut.

Update: added a cut out slot so you don't have to feed it through like a doofus every time.
Update: after living with it for a while my filament caused enough friction to rub through the arm. Trying a fix to the chamfer.
