SummaryAmended flextruder reworked to direct feed for use on Mostly Printed CNC with E3D volcano may be an adjustment for 3mm version to come used same for both 3mm and 1.75 but still have print test to confirm works correctly with 3mm waiting on delivery of hobbed pulley's for 3mm testing as feels a bit tight with non hobbed pulley. Amended for better locking of E3D with two M3 screws and nuts, not a great deal of pressure on this connection but a little more solid. left both versions available but prefer improved version.Print SettingsRafts: Doesn't MatterSupports: Doesn't MatterResolution: 0.25Infill: 50%
