Rounded 40mm Fan Mount for NEMA 17
thingiverse
To fit a 40mm fan on my MakerGear Prusa Mendel motors without dismantling the printer, I adapted a fan mount design found online. Starting with the x-axis carriage mount (http://www.thingiverse.com/thing:13343), based on an earlier model (http://www.thingiverse.com/thing:10032), I flipped the orientation to suit my motor setup. A video showcase is available at http://www.youtube.com/watch?v=ohoYNmLKtcY&feature=plcp. For each fan mount, print two copies and secure them with four M4 or M3 screws, nuts, and washers. Ensure clearance for the extruder's z-axis movement. The openscad file is included for adjustments, though parametrization is limited.
