A1 Mini Gridfinity 7x6 Bin (5U) Dovetail Split Fit

A standard 7x6 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, and I also included a Bambu Lab P1S profile for anyone printing on a larger bed. 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 7x6 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.

Assembly
