Prusa Mmu1 layer fan shroud

thingiverse

This is the improved fan shroud for Prusa Mmu1. It improves the cooling a lot. It works much better than the stock shroud. Print with automatic variable layer height on the Prusa slicer. It has internal overhangs and you can avoid detached strings this way. I am still using Mmu1 because it works very well. It is based on the fan shroud of this printer which I also have. https://www.thingiverse.com/thing:2921021
