Prusa i3 Pro X Parasitic fan duct

thingiverse

This is a removable parasitic fan duct for the Prusa i3 Pro X (from Geeetech). It utilises the exhaust from the existing 40mm x 40mm fan on the extruder assembly. Once installed, the part stays surprisingly cool to the touch so can be made from PLA and used in conjunction with a heated bed. Note that the fan stays on 100% of the time but this piece can be removed in seconds when not needed. Great for leaving fan ports on your motherboard free. Print Settings Printer: Prusa i3 Pro X Rafts: No Supports: Yes Resolution: 0.2 Infill: 20% Notes: Print upside down with small end of nozzle in the air and the bottom of the bracket flush on your bed. Not tried ABS Works well with PLA Post-Printing The small end of the nozzle will print with a bit of support material inside. This is admittedly a pain and will require a drill or equivalent to effectively remove. If the fan duct requires slight adjustment (a few mm for example), don't forget that you can gently warm the piece to adjust it to your liking.
