I have a set of handy 4-11mm wrenches that needed a place on my storage wall, so here is a somewhat organic looking holder for the set.
The handles are fairly inconsistent in thickness, so the slots are drafted to allow you to press each wrench into the corresponding slot so it has a snug fit.
If you're interested in the wrenches, the ones I bought as Zenith Industries ZN502008 appear to no longer be sold. However, there do appear to be several similar brands still for sale (I assume they all come from the same factory). They're definitely not precision tools but some times it's handy to have something other than pliers to hold onto an m3 nut.
As with most of my models, you can find the source here at Onshape.

Designed from scratch to be compatible with the honeycomb storage wall spec.
