Yet another Gridfinity Bambu swatch kit holder. This one is stackable, half height, and angles the swatches so they're easy to slide out and the labels are visible. Press fit magnets.
Glad you like it! There are a couple of existing Gridfinity lid models with 3x4 sizes. Since this design uses the standard stackable lip, any of those should work. This one looks promising: https://makerworld.com/models/129828 I also saw one for a lid that snaps on, but it'd need some work to fit 3x4 bins. Let me know if these options don't work and I'll see about remixing something.
Only downside to this one is that the text is upsidedown...
otherwise it's great, compact but can still see them all and easy to remove one if you want.
