This is a custom spool-holder mount designed specifically for Bambu Lab’s 200 mm filament spools.
The model is built around a 22.5 mm tube, which I used from a standard curtain-rod support.

However, the design is fully parametric:
If you download the included Fusion 360 file, you can easily adjust the dimension by modifying the parameter tube_diameter to match any tube size you prefer. The rest of the model updates automatically.

For extra stability, the mount includes optional M6 threaded-rod slots. These holes allow you to insert M6 studs to lock the tube securely in place—completely optional, but useful if you want a more fixed setup.

Perfect for clean spool organization, adaptable setups, and anyone who prefers fully customizable hardware.
