Anet E12/E16/ET4 Part Cooling Fan Duct for shorter hotend

This is a remix of El_Terla's excellent work. It's just shorter so it won't hit the build plate when using a cheap MK8 hotend made for Ender 3. Fits right in and uses existing screws. All you need is the printed part.

Print in PETG if possible with no supports. NOTE: If the bottom is angled, please rotate so that it is flat on the build plate! You have to do this for the E16 one.

Variation for E12/E16

Note the position of the tabs on the lower left of the part cooling fan. If your fan looks like this then use the Anet E16 fan duct. This one is shorter than El_Terla's duct.

Variation for ET4 Pro

If your part cooling fan looks like this then use the ET4 variation. This duct is also 4mm shorter than the E16 one.
