This remix accommodates larger screw head sizes at the expense of a 33% increase in bracket thickness.
Print 2x in PLA/PETG (or ABS/ASA for higher temp tolerance) with 10-15% infill.
To install: remove the 4 rubber feet from the charger, align brackets over the holes, and attach with ~40mm screws. Then use 8 additional screws to mount the brackets to a wall.
