After starting to delve deep into the hobby of 3D printing, I realized magnets are fairly frequently used. After I purchased some that came all stuck together in a single plastic box, I designed this. It's nothing special, but hopefully someone can use it.

The lid slides from top down and may take a couple of ins and outs before it'll slide in smoothly as it was sized to fit nearly perfectly.

Model in photos was printed with Hatchbox Matte Grey PLA.

Both lid/case oriented flat side down with no supports. My slicer (bambu) suggested supports for the numbers, but I had no issues with the overhangs on my Bambu P1P. Your experience may vary.

Note: If there are any other commonly used sizes of magnets that you think should be added to the design, let me know.
