This is a small modification on the stock Prusa i3 Mk3 Einsy base and door to accommodate a 40x40x10mm Noctua fan. You'll need two 3mm bolts (about 15mm long I would guess) and nuts. Mount the fan so it blows out as an exhaust. It takes the stock hinge, you will need to print one of those if not upgrading.
Recommend PETG or ABS. I used Atomic Filament Carbon Fiber PETG.
I've printed it and it prints fine, fan fits great and the door clears, and 5v power is available and also works fine.
As for power, use the Noctua NF-A4x10 5v fan and connect to two unused pins on the P3 connector pins 1 and 7, just above the filament sensor. See included pic with pins you need colored in. There are probably also 5V pins on the Pi connector if you're not using that. Option B is to source a 24v 40mm fan (Noctua doesn't make one, but they're out there).
