Description
This is a remix of EdwinGr's model (https://www.crealitycloud.com/model-detail/filament-guide-pulley-ender-3-v3-ke).
Motivation: I found EdwinGr's model has extra tension on the filament due to the small diameter of the pulley/wheel. Therefore, I use a much bigger wheel in my design to reduce the tension force in the filament.
Furthermore, I add a second part to strengthen the roller mount. My design works well even in the case of tangled filament spool.
For installation, you will need an M3 screw (no requirement in its length).
Printing:
Material: PLA
Infill: 25%
Support: None
Differences of the remix compared to the original:
Use a much bigger wheel.
Make the roller mount longer.
Add a second part to strengthen the roller mount.
Updates:
2026/01/16 Add "mount_part1_v2.stl":
v1 is ok, but the filament may jump out of the pulley occasionally.
v2 modified the dimension slightly to fix this issue.
