Fan duct and mini blower holder for Sunhokey Prusa i3.

thingiverse

I received my Sunhokey Prusa i3 yesterday and while it's a fantastic value for money it needs certain mods to be a good printer. This mount replaces the two included printed fan brackets and both ducts the cold end coolant airflow around the heatsink and lets you mount two small 35x35x10 mm blower fans. Other blower fan dimensions will probably also fit as long as they aren't a lot bigger. I don't have others to try with. I used two Unitedpro B3510X05B 5 V fans connected in series to drive them both with 6 V. I design my parts around things I have lying around. The blower mounting tabs are made for M2,5 screws of the appropriate length for your fan. Self threading will also work. Figure it out. The other screws are M3x12 and M3x16 from the Prusa i3 kit. Print Settings Rafts: Doesn't Matter Supports: Yes Infill: I use 15 Notes: Print in the orientation it opens. Use supports under the whole thing, except for the to tabs which contact the bed. Sorry, but I can't be arsed to make it more printer friendly. Most of the supported surfaces are hidden by the cold end fan anyway.
