[https://www.printables.com/model/35701-fastenal-storage-bin-inserts]

I bought a bunch of these Fastenal/TruForce 0569279 4.125" x 5.325" x 3" storage bins but forgot to get inserts to separate out small parts. So I designed inserts to fit.

These two inserts are not intended to be used together in the same bin. Use one or the other. I may update the models with notches to allow interlocking the two inserts at a later time or feel free to remix.

The inserts are approximately 1.25" high. You can scale the y-axis to make them a bit taller but if you go too tall, the fitment will be off since the interior of the bin has no right-angles.
