Threaded dust filter colorizer

Sick of just plain ol' white filament

I did a mashup remix of two awesome designs, a filament colorizer (says for 3mm but works great with 1.75mm) and the "you need one of these if you 3D print" threaded dust filter

I found that if I leave the permanent markers on the filament and my 3D printer not feeding filament thru the extruder the acetone in the ink will soften/weaken the filament causing it to snap...so best bet is to start a print and as your 3D printer starts extruding put in the permanent markers...I print in ABS...PLA shouldn't have this problem

cap can be found on the original threaded dust filter thing
