Prusa MK2 MK2S Peek-A-Boo Fan Shroud

thingiverse

I aimed to offset my fan in this way so I could create space for viewing the print from the front of my MK2S printer. This setup saved me a significant amount of time, as all I had to do was add the gap. To be honest, I'm not entirely convinced by the exit design for the ducts, especially with an E3D sock. They are rather far from the extruded plastic, lack directionality, and are partially obstructed by the sock. Nevertheless, I just achieved a flawless 50mm bridge print, so it can't be all bad. Perhaps I'll modify the design further in the future; maybe not, we'll see. I conducted a test print of both pieces (check out the description for the second piece) using PLA to verify fit and function. Having printed several hours of PLA prints now, the heat doesn't seem to be affecting the parts... I might just use the PLA components instead of remaking them in ABS/PETG. We'll see if they hold up over time. When assembling this, attach the two printed parts first (this is crucial), then mount it on the printer, and finally secure the fan to it. To get the fan to reach without disassembling the entire cable whip, gently pull a little slack on the wires (you should be able to obtain a couple of millimeters of extra length) and then unhook the wire from the small plastic tab/guide on the fan itself.
