For whatever reason, the very common Dewalt DCB101 charger for their 20v lithium line of tools, does not have any provisions to be wall mounted. This mount is not a perfect fit, but does secure the charger solidly, so that it will not move when installing or removing the batteries.
Does not require any support material or raft if printed left side against the bed. I printed it in PLA at 0.3mm/layer. The charger does not get warm enough to warp the PLA.
