Ender 5 Max "Arctic Fox" V2 - Cooling Duct Upgrade

Welcome to version 2! This is the new and improved version of my original Ender 5 Max toolhead cover.

There are a few notable improvements in this version.
- Shell thickness has been optimized to be more consistent and a touch thicker at the front.
- All corners are now properly rounded, including the interior ones.
- Fan position, fan mount locations, and fan duct paths have all been improved.
- Fan mount no longer requires supports during printing, has better sized holes for heat-set inserts, and is more robust overall.
- Fan duct is now FULLY REMOVABLE! You can pop it out anytime by spreading the side walls out slightly and it will slide straight out the front. No need to remove the fan. There are two small clips (not shown in the images above) which hold it in place.
- STEP file support is here! You can now print this model directly from the STEP file for higher quality, or use it to remix the object to suit your use case. An STL copy is still included for convenience.
- No more custom support structure. You will need to support the very top of the model when printing it, but that is all. I recommend using tree supports for this.

It is recommended to print this in something heat resistant. Do NOT use regular PLA. ABS, ASA, HT-PLA, or other high temp materials will be necessary for the fan duct. The toolhead cover only needs to be able to withstand the ambient heat of the printer if enclosed.

NOTE: If your printer cannot handle high temperature materials, you can buy these from my [Etsy store], printed in ABS or Polycarbonate Carbon Fiber (PCCF).

When printing this model:
Use 0.2mm layer height (or thinner for a smoother look)
3 walls for 0.4 nozzles, 2 for 0.6 nozzles
Add supports to the areas in the picture above.

You will need 3 M3x16 screws and 3 M3x5x4 heat set inserts to mount the fan.

Changelog:
- (3/22/26) Minor adjustment to fan mount position to center it better.
