Sherpa Mini Dragon

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4936587.

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.
