Low Friction Spool Holder - Bambu P2S - V1
Print Profile(2)
Description
Low Friction Spool Holder - Bambu P2S
This spool holder replaces the standard friction-based mount with a dual-bearing system designed specifically for the Bambu P2S.
By utilizing two standard 608 bearings, the unit allows the filament spool to rotate with near-zero friction, greatly reducing the mechanical load on the extruder. The result is a more consistent filament tension, which helps prevent under-extrusion and surface artifacts.
Key Benefits
- Mechanical Efficiency: Minimizes the force required to pull filament, protecting the extruder gears from unnecessary wear.
- Stable Feed: Smooth rotation prevents the spool from jerking or jumping during rapid retractions or high-acceleration phases.
- Dual-Side Compatibility: Designed to fit the specific mounting footprint for both the left and right side positions of the P2S.
- Original Hardware Integration: Fully compatible with the original spool holder's PTFE tube connector, a longer tube is needed, and the original slide-on mounting bracket, ensuring a seamless path from the spool to the toolhead.
I recommend this to be printed out of at least PETG, as it sits right above the exhaust port and will warp if PLA, ask me how I know :)
Feedback
If you find this model useful, please consider leaving a rating or sharing a photo of your make. Feedback and suggestions for further optimization are always appreciated as I continue to refine the design for the community.
This is Version 1 of the design, with improvements planned for the future.
CHANGELOG
04/03/26 - Added a relief hole to allow the bearing to be pressed out
05/03/26 - Updated support settings for a cleaner surface finish
13/04/26 - Added PETG-CF print profile for heat resistance and stiffness
16/05/62 - Increased infill from 15 to 25% to increase stiffness and reduce deflection under the weight of a full spool
