This is a simple nozzle holder that will take 4 E3D v6 style nozzles or anything that has a 6mm thread on it. I made it for my P3Steel, but it should fit any machine that has a 3mm frame.
8/9/2016 - Added a 6mm frame option
Printed thick and hollow at about 50mm/s, was done within 20 minutes. any settings should work.
