Upgrade Creality x BEN2C Nautilus Fan Duct for K1 MAX 3D Printer, High Performance 360°Cooling Fan Duct, Better Overhang Printing Quality, High Temperature Resistance

I was skeptical, but this toolhead cover is pretty great. Install was super easy(easier than original cover) Fan noise and vibration from tool head is gone. I still use the bed side fan but this has being in the same room as the printer mor enjoyable. Is it worth the $30, to me, absolutely.

Works great. Good overhand quality. Blob of death killed two of my stock fan ducts. Solid replacement.

I'm giving three stars as the shroud worked as intended but ended up causing bed leveling issues. The shroud was great until it wasn't. Worked fine for approximately 10 prints before I started having issues. While its intended purpose was there, the part that surrounded the nozzle was giving false bed level reading when the calibration touched directly in front of the tip cleaner. This was as a result of the fan drooping down with consistent use and impacting the tip cleaner and making the bed mesh show 1mm higher at that point than the next highest point. The nozzle wouldnt get low enough to lay down a good initial layer on larger prints in vicinity of the cleaner. All centrally located prints didnt have issues. If you mostly print small items on the K1 or K1c then you are good to go buying this. For larger prints or multiple objects that come near the cleaner brush on the a or b creality plate (unless you go full klipper and eliminate the cleaning routine to delete the brush) you will have issues time and time again.

I thought I might be able to fit this to my Aquila but haven't had the time and went another route. The head is very lightweight and really cool. I love printed parts for 3d printers, it just makes sense. Even some of the packaging was 3d printed.The description say the material is "PA12" which is a nylon and seems durable but they use a very odd wording to say it is 3d printed, "Multi-Jet Fusion technology with PA12". In fact, they do not mention anywhere that it is 3d printed in the description. ?? For that I deducted a star because it seems a bit dishonest, especially since all the pictures are 3D renders and not of the actual product.Come on Creality...

Light weight quality improvement for the printhead! Massive improvement in bridging and string art. Comes with tools and amazing instructions as well as a couple of spare parts! Take your time installing and pay attention to the instructions.

UPON OPENING THE "UPGRADED" COVER. I IMMEDIATELY FELT RIPPED OFF!!The "upgraded" cover is just SLS printed (very thin quality with noticeable layer lines) and NO FAN module is provided. The instructions make the buyer use their old fan from the default Creality head unit. While trying to print a benchy boat for a test run, the new "fan duct" somehow caused all the filament to become stuck to the nozzle and then back flow into my printer's head. Thus, causing the newly installed cover to become cracked and have melting spots from the hot PLA+. For an "fan duct" that is advertised to withstand "high temp" the Ben2C could not even print simple PLA. SMOKE began coming out of my print head.I have to carefully disassemble the Ben2C and printer head again and manually pull off all the melted brown PLA+. Got burn marks on my fingers from this.For a $40 "upgraded" print head, Creality and Ben2C seemed to put a whole $5 into product development, printing and research. Plus, they could not provide a $2 fan module off of Temu.

If you upgrade your K1 Max to use CFS, forget it. The fan duct will get in the way of the hopper. I'm keeping this to see if I can work on something that will fit this.

The product fits well, though you must remove the fan from your old shroud and install it in the new one. Verifiable air flow all around the nozzle. Easy to install, looks and feels well made. Very satisfied!
