In Place Desiccant Container for Bambu Labs Spools

I have tried a few different desiccant holders for my Bambu Labs spools, however none of them really suited my personal requirements.

• To be easy to install
• Ability to be added to an already full spool
• DOES NOT need to be removed when refilling spool
• DOES NOT protrude from the faces of the spools
• Higher surface area

With these goals in mind, I looked around, and found many with some of the ideas I wanted, but nothing with all. So I decided to create my own.

My design takes some inspirations from the Bambu Spools itself, with holes around the top that lead to the inner core, where there are plenty of open holes for airflow. The inner code piece is a self contained piece, with the desiccant locked in place with a small screw in lid.

To install, all you need todo is slip the small sing inside the end of the spool that has the lip on the inside (The gif in the images shows how this is done), and then slide the desiccant capsule into place, and screw down with the lid piece.

Once in place, you are able to twist apart the spool, unimpeded by the desiccant holder, while it is still easy to remove, if you need to use a pass through spool holder etc. It will not protrude past the spool, so you can still stack them flat etc.

I have also tested leaving these in place when drying PLA, at 50*c for 12h, they seemed to have no issues, however at 55*c for 8h, I did notice the outer lid getting a little soft, so requiring tightening again, I would recommend keeping the drying at 50*c while using these, or loosening them a little if you plan on using PLA.

I have a funnel also that screws into place to make it easy to fill them, I will upload it shortly.
