This is a pretty straightforward 2x6 Gridfinity bin for storing the Hardell 6" calipers. The only downside to this model is that you can't stack more bins on top of it. However, I'm including the original CAD file in case anyone happens to be interested in remixing it. It was created using the FreeCAD Gridfinity workbench, so you probably need to install the addon before you can edit the file.
The author marked this model as their own original creation.
