This model is a direct result of checking the fitment of the screw cap on the https://www.printables.com/model/462564-bambu-lab-400g-spool-weight-dessicant-or-batteries and getting it stuck. 

I have included these files:

FCStd for FreeCAD version 0.21.1 (The file is parametric and you can fine-tune it if you want.)

Step, STL

3mf for Bambu Studio version 1.7.7.89

There are no gcode files, they are annoying.

There are no special print settings or a required filament type. If you need to use supports then the model is upside down on the plate :(

I used some Voxel Black PLA and pretty much the standard settings in Bambu Studio for Generic PLA. It takes about 36 minutes and 16 grams of filament to print with my settings.
