I wanted a desiccant try I could fill with fill with sila gel pellets and screw shut because I kept spilling the ones without a locking lid. I also wanted the bottom to be perforated to maximize airflow when I put it in my dehydrator to recharge.

Uses (up to) M3x12 screws to hold the lid in place, they should self tap but I've also included square nut pockets on the bottom if needed. Screw heads will be recessed so as to not interfere with closing of the desiccant niche in the AMS. Should require no supports to print.

Suggest PETG/ABS/ASA to higher temp resistance in the dehydrator but PLA would work in a pinch if you dry low temp and slow.
