RockShox Remote Spool Casing – Durable Replacement

Why I Made This

On all the RockShox forks I’ve owned, the small plastic spool housing eventually broke—usually right at the spot where the ferrule sits. To avoid replacing the same weak part again and again, I designed a stronger replacement casing.
As a bonus, this also lets me bring some color onto the bike.

What’s Included

• .3mf file prepared for BambuLab X1C
• .stl files for general 3D printing
• .sldprt files if you’d like to adjust or remix the model in SolidWorks

Printing Notes

• Use a durable material that can handle sun and heat (e.g., PETG, ABS, ASA, etc.).
• Print it strong → multiple walls, and I, personally, went with 100% infill (the part is small).

Hardware Needed

• M3 brass insert – 6 mm
• M3 screw – 8 mm (worked perfectly for me)

Installation

1. Pull out the shifting cable with ferrule.
2. Remove the old plastic housing (loosen the grub screw).
3. Keep the existing spool in the fork.
4. Place the new printed housing on top and secure it with the M3 screw (no need to overtighten).
5. Push the cable back in — it can be a bit tight, but it will come through.
6. Re-tighten the shifting cable and fix it with the screw again.
