Built this Toolhead to meet my requirements of using a Sherpa Mini Extruder with a solid mounted Dragon Hot End, Dual 5015 blowers and a linear rail. Wanted to have it easily printable and keep the weight as close to the linear rail as possible. My setup has nothing blocked the left and right side of the printer...so decide to mount the blower low and parallel to the rail (bonus, looks like eyes of a Dragon head). I also wanted to keep the direct drive extruder close to the hot end.

Machine parts.

• Dragon HotEnd (SF or HF)
• Sherpa Mini Extruder
• 2 x 5015 Blower Fan
• 1 x 4010, 4015 or 4020 Fan

• 2 x M3 16mm for 5015 blower mount fan duct

Fan Duct mount.

Option 1

• 2 x M3 12mm for mounting Fan duct to main body
• 2-2.5mm solid wire approx 40-45mm long (used old coat hanger) for aligning fan mounts to main body

Option 2 + 2 x M3 or M2.5 70mm bolts with nuts, you can mount the fan ducts all the way without the coat hanger.
