This thing is a Desiccant Container in the shape of a 200mm diameter, 14 mm thick disk. The same diameter as most filament spools. The container holds at least 200 grams of Desiccant.

It is designed to go in a dry box and when a recharge is needed, you can simply put several of these containers in your filament dryer at once.

You probably shouldn’t print this in PLA as it will become deformed in the dryer. PETG or something at least as heat resistant is suggested. The containers pictured are printed in Bambu Lab Black PETG-CF.

The fit of the joining tabs are precise. This model is sized to fit together perfectly when printed in Bambu Lab Black PETG-CF. You may have to adjust the size of the lid if using other materials.

It is suggested to print the pins at a layer height of  0.16mm, while the rest of the model should be printed at 0.2mm.

Thanks for looking and happy printing!
