I loved the idea of the coin cell box by @mac310, but I also have a few LR1130 that I wanted to put in there. Fortunately they have the same diameter as LR44 so I only needed to change the depth of the slots.

I also did a few more modifications to make the box more comfortable to use:

• Added a guide to make it easier to place the lid on the box.
• Included a cutout to indicate the correct lid orientation.
• Added a groove for easier box opening.

Print settings:

For my prints I used the following print settings:

• 0.2 mm layer hight
• 3 walls
• 15% infill (rectilinear)
• Arachne wall generator

Assembly

You need to glue in 4 6x2mm magnets. Make sure to get the polarity of the magnets right.
