I've got some filament in 100 liter tubs, and I wanted a bigger desiccant container to keep them dry. So I designed this canister. It has a bayonet-style twist-off top. I also made the funnel to make it easier to pour beads without spilling them. The funnel has the same bayonet latch. The canister holds 235 ml (1 cup).
I modeled this in Fusion 360. I've included the CAD files in Fusion 360 and STEP formats to make remixing easy.
UPDATE July 31, 2026: I made a new version with three latches around the perimeter instead of two. See the photo with the periwinkle blue funnel. The new version latches more securely, but it's not compatible with the original design. If you're starting now, use the 3 latch version. If you already have a two latch funnel, you might as well stay with the original.
How to Print
The design is optimized for a 0.2mm layer height and 0.4mm nozzle. The .3mf files are already oriented for printing. The funnel cap file is in two parts; you can use different colors for the cap part and the funnel part.
If you use color indicating beads, I suggest a clear/natural filament so you can see the beads inside.
