Description
This TPU driven support shaft assembly for the Bambu Lab AMS improves spool grip and rotation compared to the stock roller.
The flexible TPU surface helps prevent slipping and ensures smoother filament feeding.
Why this mod
Common AMS issues this upgrade addresses:
- spool slipping during rewind
- inconsistent filament tension
- poor grip on cardboard or lightweight spools
- Noise reduction
TPU provides better friction than the stock plastic roller, improving spool control.
Features
- designed for Bambu Lab AMS
- TPU roller surface for improved grip
- smoother spool rotation
- compatible with standard spools
- simple replacement for the original driven support shaft

Required components:
- 693 bearings (3×8×4 mm) (you can reuse the bearings from the old rolls)
- 3 mm rod → 80,7mm
Recommended print settings
- material: TPU 95A
- layer height: 0.16–0.2
- 5 walls
- 40 % infill
Compatibility
