Remixed a pegboard design for the wlc100 to instead mount directly to a honeycomb storage wall.
Fittings on the back snap directly into an unoccupied hex cell; if you need a variant that will plug into a prior insert (e.g. like a hook pin would do), the openscad source has an option for that, but I've not yet printed/tested that mode.
The author remixed this model.
