This is a 6x2 Gridfinity frame insert, that fits snugly into a 12 inch toolbox from
Dollar Tree. Link Here → https://sameday.dollartree.com/store/dollar-tree/products/22960189-tool-bench-hardware-hand-held-portable-mini-tool-box-each
It holds exactly 12 units tall, and has some great price to storage ratio. It is $1.25 at Dollar Tree, then around $1-$2 in filament. Now you have a portable and closeable storage solution! It will have a tiny gap in between Part 1 and Part 2, this is normal, the bin is flexible and you should be able to put your bins and other gridfinity things on top of the crack. It has space for 6 inch/150mm calipers on the side. Even when all bins are full, the calipers have a nice space. It also has an extra pocket for small parts, but this is not that accessible with all 12 height units used. I would love to see remixes or any input about the boxes. This project took a few revisions and some time in CAD, so If you like it, drop a picture of yours!
The pictures show the box with bins that go to 6 tall. This box will work with 12 tall though.
