UPDATE 2025/01/19:
It seems my model got messed up prior to uploading to Printables. I have uploaded now a fixed model with a battery gap of 3.75mm (on paper, which is the loose fit) and will also recreate the tight fit model (3.45mm slots) once I can test it.
Sorry for any inconveniance caused and thank you to user @Prokop_1180654 for pointing it out.
UPDATE 2024/05/01:
Added additional 0.15mm tolerance to the slots for an easy ejection of the Batteries. You can now choose between the loose or tight version.
Description:
Its a bin. Surprise! And it holds up to 21x CR2032 batteries in a two by one Gridfinity format. On top of that it is stackable when filled. Solves my storage issues.
