Ender S1 Sprite HS air flow guide for Starlex DHB 22.5 hotend

To keep light weight the S1 Sprite Heat Sink Extruder mounted with the Starlex DHB 22.5 hotend, we machined the Heat Sink to improve the air flow cooling and therefore need to print this air flow duct.

PTFE tube might need to be shorten at the limit of the rigid hole. 

The Heat Sink Connector will be in light contact with the PTFE tube when mounted to reduce maximum filament path space.

Enjoy quick nozzle swap and increased melting zone similar to a volcano nozzle in the same space as the standard Mk8 nozzle (+0.8mm)
