Fan Mount for OLD Prusa Mk3 Power Supply

prusaprinters

<p>My very first Prusa still works on in the shop and I happened to rest my hand on the power supply the other day. &nbsp;It was really hot! &nbsp;So I designed this.</p><p>This part has two holes to mount the 80mm fan and then just slips over the top of the silver PSU. &nbsp;(It does not fit on the black PSU as typically mounted.) &nbsp;It was designed to print easily and not use unnecessary material.</p><p>I printed it in ABS at 0.2 mm layer height, 2 perimeters, and 20% grid infill. &nbsp;The holes are designed to have M4 cap head screws self tap and hold snug.</p><p>I'm using a 12V, 80mm fan I had laying around, and just ran some wire from my ATX breakout board to power it (independent of the printer).</p><p>You probably want to cover the vents in the PSU that aim towards the build plate. &nbsp;<i>[see edit]</i> I used a strip of black electrical tape.</p><p>&nbsp;</p><p><strong>EDIT:</strong> &nbsp;The electrical tape I used was really old and the adhesive failed after a few prints. &nbsp;Now I'm using aluminum duct tape (which I had lying around) instead.</p>
