Bambu Labs Reusable Spool (Splined)

WARNING After using these for some time it has become clear that the sides are too flimsy - as the spool turns you can get filament stuck down the sides. I've had several prints that were very painful to finish because they repeatedly paused when it was unable to load or unload the filament due to jams caused by filament becoming wedged along the sides. This even happened with perfectly-wound refills from Bambu. Description This reusable spool for Bambu Labs filament refills is based on a splined design that uses much less filament, which I then modified to make the label placard just a little bit larger so that it fits the labels provided by Bambu Labs. Print Instructions Here are the settings I used. I doubt it matters if you deviate from these, but there's a lot of surface already touching the plate so I'd definitely avoid brims. Sparse infill density: 20% Sparse infill pattern: Gyroid Infill direction: 90 Wall generator: Arachne Brim type: No-brim Enable support: No
