RHD CS Nozzle Fan (Part Cooling) for Prusa Mk3s PitStop Extruder

thingiverse

A remix of the RHD CS NOZZLE for the pitstop extruder. Angle and attachment of radial fan was altered. A spacer was created to adapt from original mounting holes. Printability was improved (I think) by an addition of a fin inside the model. Airflow altered due to the new positioning of the fan so changes were made to improve this. [This has not been verified in CFD] I have tested the fit on my V1 Pitstop and there are no issues. A little extra fan cable slack would do no harm. I printed it with no supports at 0.2mm with a draft shield and DETECT THIN WALLS on! You don't need to but I cleaned up some stringing and clipped the two thin walls that support the corners close to the opening for the fan. Firstly insert the m3 hex nuts into the blower spacer and then use 2 m3x8 (head included) countersunk screws to secure the blower spacer to the extruder. I used the original screws and washers to mount the fan to the bracket with 2 m3 hex nuts pushed into the back.
