Sterilite 6qt Gridfinity Baseplate and Container

This baseplate brings the Sterilite 6qt 1642 container into the Gridfinity ecosystem, allowing a 3x6x15 volume of use.

As pictured, if using standard bins, a total of 15 units in height can fit - and near perfectly. This can allow the container to tip without losing the contents of the bins inside if using the full height.

Two (identical) parts are needed for the full container to be used, no glue required.

The baseplate is suitable for 3D printing in PLA. The weight is mostly supported by the container, so it's pretty sturdy.

Please Note:

If you see the photo of only the baseplate and container, where the plate looks uneven due to the container's flex, this is not an issue. The containers slightly flex upward in the center, once weight is added the baseplate will hold flat.

While I've tested this to fit in many containers I've had ranging from a few years to a few days old, it is still possible a container may not fit the plate in. It should at most require light sanding on a catching edge. This is why the corners are slightly curved in on the model, hoping to account for the wide variability in the container quality.

Fusion360 File:

I've included the fusion file with 3 variants of the panel. While the Bin in the design is very close, the large margins of manufacturing tolerances are to be noted. For instance, in the corners of the panels, you'll note that the panels' corners are bent inwards. This is to account for some bins having slight warps.

If you have a printer with a 300mm+ area, you can print the panels as one piece. There's a construction plane under ‘Construction > MIRROR+SPLIT_PLANE’ that can be used to mirror or split a body; it's just a copy of the XZ plane.
