Fits the ridgid charger versions R840095 and R86092 and mounts to pegboard with ~25.4mm (~1 inch) center to center ~7ish mm holes.

Note: I would print on the side, as you want the layer lines setup so that the pegs can't snap off with either putting in the pegboard or putting on the battery charger.. Printing on the side allows the little pegs to share the same perimeters as the backplate if that makes sense so they're muuuch more strongly attached and unlikely to break.

Use tree supports, they work pretty good.
