I remixed the fan duct by "amass3d" to combine it with the original E3D V6 hotend.
4x M3x12 (allen screw) - for the "Halter"
2x M4x25 (type doesn't matter) - for connecting "Halter" to "Aufnahme"
2x M4x8 (countersunk screw) - for tightening the "Aufnahme" to the stock carrier
2x M4x20 (allen screw) + 2x M4 nut - for connecting "Aufnahme" and "Fan Duct"
1x M4x25 (type doesn't matter) + 1x M4 nut - for the 5015 blower
(2x M3x8 (type doesn't matter) - for the cable chain)
Have a nice print ;-)
P.S.: Take care of the reduced Y-size of about 20mm!!!
