Ok, make one.
* 65g of material.
* 8h+3.5h of printing time at 0.25mm/layer
* larger then I thought
* slight warping.
* will create modified ones when other objects to design are done

Cool... How long does it take to print one of these?

Lets make a system of these!

* double-wide version,
* version with hole for a countersunk screw in the back to attach these to a wall in your workshop,
* end and edge -variants that have no attachment-points on one/two sides,
* double-depth version for long screws or to use from both sides,
* a grip that can attach to the top-side of a row of these for carrying,
* hex-key/drill-bit/screwdriver-set board that can attach to a wall of these on both sides
* adapter to hand double-depth -versions below normal version
* ...please add more ;)

This is a clever and attractive solution, I will be printing some of these in the future.

may be usefull too if you like this one.

Cool!

Just combine as many of them as needed.
Making doube-wide or 2x2 -sized versions should be trivial
to stack items of different sizes. :)

Love this, a really good idea. Just grab yourself a label printer and your sorted. I guess you could even print your own dividers or inserts for things like hexagonal tool bits.
