i3 MK3S fan upgrade

thingiverse

Print the included g-code immediately. Replace the original fan with a new one for your i3 MK3S printer. You'll need to secure it with an M3x50 screw. Don't forget to have some screw taps on hand as well. For optimal performance, use PETG filament with a minimum of 4 perimeters and 30% infill for R4 or R5 prints. When building the fan shroud, opt for ABS filament with 100% infill and 4 perimeters instead. This assembly has been thoroughly tested and proven to be fully compatible.
