Try this model out, it's not perfect and I'm hoping someone can remix it to make it looks like something. I modeled it to fit the drill bit inserts out of a dewalt drill bit set. Let me know what you think. The storage box beneath may be somewhat useless, but I'm hoping someone can run with this concept.  "Explode" the step file in your slicer so you can get the individual bins & inserts to print seperately.  I took some inspiration from https://makerworld.com/en/models/933548-dewalt-tough-case-drill-bit-gridfinity#profileId-897924 , and https://makerworld.com/en/models/828494-gridfinity-2x4-dewalt-drill-bit-organizer#profileId-772505.
