Prusa MK3 fan duct

thingiverse

I swapped out the Prusa MK2 fan for a modified version that fits perfectly on my MK3. The original fan worked like a charm on my old MK2, which only cools prints from one side just like the new MK3. This mod fits snugly and performs well. Note that I added a cutout on the side to accommodate the PINDA probe. I've also included an updated file that attaches the fan to the print bed as a support, preventing it from twisting out of position or dragging on the surface. The latest update gives the shroud an extra 1mm of clearance to avoid hitting prints, ensuring smooth printing.
