Prusa MK3S Dual Fan Duct
Description
I struggled to get good looking overhangs (PLA/ PETG) with the stock fan duct on the prusa i3 mk3s+ and tried other ducts but i still had issues. I ended up splicing in a second fan but the existing prints for a dual fan duct were either very cumbersome or they blocked my view of the nozzle! This mounts up with the existing mountig points and other than splicing in the second fan there is no other modifications required. This might require some of the spare hardware that came with your prusa mk3s. fasteners required: 3x M3x20mm 3x M3x18mm 1x M3x10mm 4x M3 hex nuts 1x M3 square nut Here is a diagram showing how to wire it up: https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-hardware-firmware-and-software-help/adding-another-fan-to-my-prusa/#post-583537 This improved my prints a lot so i figured i would upload it. I hope this helps you too!
