A standard 7x3 Gridfinity bin that actually fits on smaller printer beds, thanks to a clean, strong dovetail split with built-in alignment tabs.
See my other models for more sizes. If you need any specific size, ask in the comments and I should be able to make one fast.
This model is a 5-unit-tall Gridfinity bin (~39.5mm tall), split into printable sections so it fits cleanly on the Bambu Lab A1 Mini, this will also fit on any printer like the Bambu Lab P1S. I've added alignment tabs along the split so the sections self-register during assembly, keeping the sides perfectly aligned and helping prevent side-to-side movement.
I couldn't find a 7x3 Gridfinity bin that would still fit on my smaller printer bed, so I designed my own.
Every model includes both a tight profile and a loose profile. I prefer the tight version because it is very snug and doesn't move. The loose version is there for anyone who wants easier assembly and disassembly or whose printer runs a little looser on tolerances.
