Silica canister for round meter

Scratching my own itch. These simple canisters are designed to use the cheap, round temp/humidity meters I found on Amazon, and fit inside the hub of most the filament spools I had laying around. So they work in a dry box, or bags with no problem.

They have an outer diameter of 50mm, and a height of 65mm. The center is 40mm.

Fill with bulk silica/desiccant, and pop in a meter. Use silica gel with a diameter of 2-4mm so they don't fall through the openings. Make sure to give them a good shake over a trash can, inevitably a few small beads will slip through.

I printed them with .25mm layers, .4mm nozzle, 2 shells, and no infill in PETG. Pretty simple design, doesn't need anything fancy. If using a bowden, it could easily have stringing issues if retractions are off.

Print instructions

Nothing special. Prints fine in PETG or PLA.
