QU-BD One Up / Two Up Nut retainer and Fan Mount

Two parts.

One clip (Nut Holder V2) which holds the nut from the stock extruder from QU-BD, so you don't need to hold the nut while you're tightening the extruder clamp.

This clip has M3 holes which docks onto a fan holder for the stock fan (or anything else you might want to make) with a couple of M3 screws. The fan holder has two ducts, one for the print, and one to keep the top of the extruder and extruder stepper cool.

All prints with no support, and even in poor resolution. Soli
