Overview
This magnetic pulley system reduces filament friction when printing with TPU or other flexible filaments inside the Original Prusa enclosure.
Features
- Dual-axis rotation:
- Axis 1: Guides filament smoothly from spool to extruder
- Axis 2 (rotated 90°): Allows the pulley to pivot and follow the motion of the toolhead
- Magnetic mounting: Attach it anywhere in your enclosure to match your filament path and workflow. Easy to reposition Or move out of the way when not needed
- Enclosed filament channel: the filament is fed through a tapered channel that prevents it from slipping out during printing.
Required Hardware:
- Bearings: 2x 32mm OD, 20 mm ID, 7 mm thickness ball bearings
- Magnets: 4x 4 mm diameter, 8 mm length cylindrical magnets
Print recommendations:
- Use PETG or other sturdy material for strength
- No supports required if oriented properly
The .step file is included so you can easily adjust the design to fit your own setup, bearings, or magnet sizes.
