Cylindrical Dessicant Box

Shortly after diving into 3D printing, I encountered the necessity to store filament and that led me to tackle desiccants head-on. I took a look around other solutions and decided to design my own. My objectives for this project were: Cylindrical and able to fit inside the center hole of filament spools I am using (~50mm dia.) Able to contain the desiccant I am using (2mm-4mm dia.) Maximize air flow through the container Minimize printing time (I need to make many of these and lots of small holes increases printing time.) This is what I came up with. It has thin walls and with a .350mm print resolution, it's all perimeter and no infill. Despite the thinness of the walls, it's surprisingly solid. (No, you can't stand on it, but plenty strong enough for holding desiccant within a spool of filament or gun safe or tool box.)
