Slightly different sizes than original fans; Apparently the HSC brand ones are a little bigger. I don't know how much, compared to the Coolcoox I have; I still don't know how big the difference is, they haven't given me the measurements, I'm sorry. That makes it a bit difficult to work on a solution, but for now it's just a case; I don't know if everyone is like that. I won't upload a variant until I have more feedback and measurements (if you could help me by taking measurements and scanning both sides with an office printer if possible, I would appreciate it)

Hello again, updated 3MF files. The first one ("Slightly Larger Fan Frame") is simply the front shroud modified to accommodate larger fans (e.g., HSC) due to manufacturing tolerances. The downside is that it relies entirely on screws, unlike the original Coolcoox fan, which is held in place by press-fit even if the screws break.

I have redesigned this cover to make it much more resistant than the original. I increased the overall thickness and split the model into several parts, looking for better support points. I added a new way to secure the fan duct for better firmness. The part cooling fan fits in by pressure, since I wasn't able to use the original screws because they always broke the part; for now I've ruled that out. The parts fit together with relative subtlety, bending slightly but without breaking. I recommend printing in ABS if possible.

The result is two versions depending on your preference:

• Magnets only (front) → quick and clean mounting.
• Magnets + front screws → extra fixation in case you want the absolute certainty that the cover won't fall off.

Additionally, I've already included in the design a PTFE protector integrated into the housing itself, to avoid having to look for another mod.

I've added three different styles (purely aesthetic):

• Hex style
• Classic Anycubic
• Anycubic + Microswiss logo

IMPORTANT NOTE ABOUT THE FANDUCTS

The fanduct designs are not mine. I've been working on remixes of these models (links below) because I'm bad at designing fan ducks from scratch and it's easier for me to edit STLs. The union of this fanduct is different from the standard on most covers; I made it looking for more strength, so use only the ones that are compatible. Credits to their respective creators. I'm leaving the links here for the available ones
