Upgrade your P1S or X1 printer with the official Hardened Steel Extruder Gear Assembly, designed to deliver consistent, long-lasting extrusion when printing abrasive engineering materials. This assembly includes the active and driven gears that feed filament into the hotend, providing improved durability and reliability over the standard stainless-steel gears.

Built from heavy-duty hardened steel, this gear set offers increased abrasion resistance—ideal for carbon-fiber, nylon, and other reinforced filaments. Instead of replacing the entire extruder unit, users can swap just the gear assembly, reducing maintenance cost and keeping the printer running smoothly.

Note: P1 Series extruder units ship with stainless steel gears. Upgrading to hardened steel gears is recommended for printing engineering filaments.

Features

  • Enhanced Durability: Hardened steel construction stands up to abrasive materials such as PAHT-CF and PET-CF.
  • Cost-Efficient Maintenance: Replace only the gear assembly—no need to purchase a full extruder unit.
  • Consistent Filament Feeding: Precision-machined active and driven gears ensure stable extrusion under demanding conditions.
  • Optimized for Engineering Materials: Designed for long-term performance with carbon-fiber and reinforced filaments.

Compatibility

  • Bambu Lab X1 Series
  • Bambu Lab P1 Series

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

It’s ridiculous…
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
When I got these pillows I was a little disappointed that they appeared to be a little lumpy. I fluffed and let them rest for a couple of days to see if they’d poof up. Finally figured this was as good as they were going to get. First night sleeping with them…my life has changed! I typically like a lot of pillows. I’m usually a restless sleeper. I fell asleep quickly and slept through the night for the first time since I can remember. No aches and pains as usual. It’s ridiculous that a couple of pillows could have made such a difference in my quality of sleep. Who knew?! I’ll buy these for every bed in the house.
