Here's a Gridfinity organizer that can hold two Samsung Galaxy Buds cases. Should work with any of the “rounded square” cases, like the original Buds, Buds 2, Buds Live, Buds FE, Buds Pro 1 & 2. Because of their new case design, Buds 3 and 3 Pro won't fit.

I designed this to fit in a corner of my gridfinity layout, resulting in it being a 3x1.5 tile size as shown in the images. This is still fully compatable with the base gridfinity baseplates, but will leave half a tile empty unless it's also half sized.

I got my half size baseplates here, from huma_meng
