This model allows you to turn a reusable bambu filament spool into a toilet paper holder.

I cut the original spool in the slicer and added a plate under so it just threads in like a regular spool.

I also added a small internal holder for the tp roll holder.

The mounts are just a quick prototype but should allow you to attach the spool from the two most outer holes in the rim.

feel free to adjust as needed
