Who doesn't love Gridfinity? I saw a few recommendations that the Multi-Use Case with Inserts needed a Gridfinity remix and I happened to think the same myself, but since no one had done it I decided to go ahead.

Currently I've only done the 2x1x1 size, but I do think that other sizes would work nicely as well. If you're interested in another size, please let me know! I'll either do it myself, or upload the Fusion360 archive for this model.

The box is relatively tight on the top, so all but the smallest of contents will remain in their bins no matter how you shake the box.

Update: I have modified the lid to slight (ever so slightly) cut out space for the bins. My print didn't have problems, but one user reported issues with this. I also added the f3z file for you to edit, should you like.
