Pushes at least 2-3x more air than the original cooling solution. Not flow tested or anything though. You will need a 6028 fan and two M3x35mm fasteners to mount it. The fan works on either 12/24v (instead of 5v) so you will need to be creative. I'm using this BTT MMB Cubic board which provides up to 3 selectable 5/12/24v fan outputs.
Adapt a TZ v6 Hotend to your MK3s+ with this modified extruder body and this modified Delta-P fan duct V2-R2 fan mount.
