I recently bought a Modifi3D and saw several holders but none for Honeycomb storage wall.

Ginger Saw provided a good model on Printables (https://www.printables.com/de/model/527846-modifi3d-pro-stand-and-pegboard-holder) but it was designed for Pegboard.

I changed the modell and added Honeycomb Holder modules in the back. No support needed, it can be directly attached to the wall modules.
