BIQU Panda Jetpack Nylon Printhead Front Cover + Cooling Fan Duct for Bambu-Lab P1/X1 3D Printers, Lightweight High Positioning Accuracy Fully Suitable for Panda Revo/Flow

The original fan enclosure is plastiwelded in place, so you will have to cut some of the plastic on the original to make this fit. Also, installing it is easy as you plug it in, and then slide the part up around the hot end. It works well, functions as advertised, high quality plastic, the fit is nominal, with some imperfections due to how the old one has to be removed. Print quality is fine, heat transfer is a non issue.

Does seem to cool faster but not much different from the original at all. Maybe works better with different size nozzles but didn't test. Og with this compared on a .4 nozzle basically the same

Seems to improve print quality due to even cooling from all sides.

The existing fan shroud was glued by Bambu Labs and I couldn't remove it because it felt like it would break. So you probably need more pieces to make the installation easy and I didn't think it was worth it.

The BIQU Panda Jet Head Cooling Fan Duct was simple to install and fit perfectly on my Bambu Lab printer. It’s well-designed and does a great job directing airflow where it’s needed. The build quality feels solid, and it integrates seamlessly with the stock hotend as well as Panda Revo/Flow setups.No major complaints, but it’s always good to double-check alignment during installation to ensure optimal performance. Overall, a solid upgrade for better cooling.

You do need to be careful removing the original. It is easy to break or crack the extruder case. The original duct is now glued in and it seems to be some kind of CA or epoxy. Nothing that can be softened with heat.Seems to provide a bit better cooling than the stock duct and certainly not doing any harm. These kind of things can be a bit subjective. No complaints and have recommended it to others.

Honestly this thing works great -- The BIQU Panda Jet cooling fan duct is an excellent enhancement for Bambu Lab printers. It improves airflow and keeps the hotend at an optimal temperature for consistent prints. The compatibility with both stock hotends and the Panda Revo/Flow makes it versatile and easy to install. If you’re looking for better cooling performance and smoother results, this is a fantastic addition to your setup.

I bought the jet pack kit, thinking it would be a great upgrade and at first it was, but I soon realized that the plastic housing of the lattice front cover is extremely fragile. It was good for about two weeks until the two top maintenance in the cover popped out. I didn’t think much of it so I put a little dab of glue to stick the magnets and I didn’t think twice about what that meant for the quality of the product. About two or three days later, I noticed a few the lettuce had cracked. I had done nothing out of the ordinary, simple PLA printing, and wasn’t like it even hit anything at all. And one day I came back to the whole lattice, completely shattered With pieces all over my belt plate. Thankfully, my printer realized the top cover was off and paused itself without causing any extra damage. I grabbed a piece of the lettuce, so try to break it with my fingers just to see if it was something I did where the cover was just super weak and I could snap it between my fingers without a problem at all. So the product is extremely weak and for the price unacceptable for how easy it was to just fall apart. Luckily I was able to take the fan guide off of it and put on the normal front cover so it still is the same performance, but such a waste of money.
