I needed a round container to hold a stack of 2032 batteries and separators. I looked at a few existing designs but nothing quite matched what I was doing, so I made my own. These can be used for much more than batteries, of course.

Included sizes
The dimensions of the included STL files are:

• Container-31mm-short.stl - 31mm outside diameter x 20mm outside height, 22mm inside diameter, 17mm inside height
• Container-31mm.stl - 31mm outside diameter x 36mm outside height, 22mm inside diameter, 33mm inside height
• Container-45mm.stl - 45mm outside diameter x 30mm outside height, 36mm inside diameter, 27mm inside height

Customization
I have included parameterized Fusion360 files so you can create any size you need. The following parameters can be altered:

• Outside diameter (d)
• thread diameter (thread_d)
• thread clearance (clearance)
• bottom thickness (bottom_thickness)
• lid thickness (lid_h)
• inner height (inner_h).

Thread Clearance
If the threads are too tight, you may need to adjust the clearance parameter in the Fusion360 file to allow for a better fit. I have found different requirements for different filaments. If you make an adjustment, you only need to reprint the lid. The clearance parameter has no effect on the base container!

Matching Lid
Choose the lid that matches the outside diameter of the container (31mm or 45mm).

4/2/2024 Update: I added an inlay to the lid so you can print color-coded lids. Simply use the z-hop method to print the lids. I also fixed an issue that caused the grips on the lid to disappear if resized too large (the number of grips should scale with the lid size now). Use Container with color Inlay.f3d for new changes.
