This is a remix to several spool desiccant containers. I re-drew this one specifically for the Bambu Lab Re-Usable Spools.
I changed the diameters and lengths for better fitment into the Bambu Lab spool. I also adjusted the threads and made them with a 45 degree thread angle so you do not need supports nor finely tuned overhangs to produce good results. I adjusted the thread lead-in and lead-outs for a cleaner look. Designed the end caps to match the hole pitch of the holes in the Bambu spool. Added press-fit features for the end caps to help securely hold them into place.
Here is a link to the silica beads I used (4 containers uses about 0.5lbs)

I added a custom infill 3MF option if you did not want to print the default circles version. You can open the 3MF and edit the following to achieve the desired result you are looking for:
