Geeetech Prusa I3 Pro B (2016 Version) Fan Duct + 3D Touch Holder

thingiverse

I've experimented with adding extra fans but found they generate too much noise. I used NAPALM's designs as a starting point and adapted them to fit around the heat sink, securing an additional cable tightly on top. The duct can also be attached with double-sided tape to the top of the heatsink. So far, it seems just as effective as an external fan when my machine runs at standard speed. I don't run my Geetech Prusa i3 over 50 mm/s because the vibration becomes too intense even with acrylic frame and anti-vibration feet installed. Having an extra fan is significantly louder than this setup. Update 2017/01/31 As requested, a reduced 10mm version has been uploaded. Update 2017/03/09 A matching edited 3d Touch Holder has been created, offset from the Geetech design by X= +15mm and Y= -3mm. Print Settings Printer Brand: RepRap Printer: GEEETech Prusa i3 Pro B Resolution: 0.2 Infill: 15% Notes: There are four triangle corners; do not remove them, as they function as seals for the heat sink corners. The triangle corners are 0.3mm thick, so set the first layer to 0.3mm and then to 0.2mm after that. Ensure the printing bed is not too high or the first layer will be less than 0.3mm.
