Spool desiccant for AMS

This little thing is a desiccant (beads) container that you place on the inside diameter of a spool while in the AMS. It's made for Bambu Lab spools, so it fits just perfect. The cylindrical container is a bit smaller than the inside diameter of the spool so it rotates inside during printing exposing more beads directly to the air. This increases the amount of humidity that can be captured as not always the same beads are in contact with the air inside the AMS.

The thing is made of a cylinder and a threaded cap. Just fill with desiccant beads to about 80% to leave some room for the beads to move around, exposing each bead to the air, as opposed to always having the same beads in contact with the air.

I printed 3 of these and placed them inside my AMS, and the printer RH sensor is showing an RH level of 1 (the lowest level). In other words, it just works!

EDIT: Use 0.12 layers if you want better threads. Does not matter to me, but seems to be an issue with some.
