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.
As always, PETG is ideal for functional prints, but PLA or anything else will work fine. Modeled in inches, so if it shows up tiny, scale up by 2540 to convert from mm to inches (Mainly an issue in Cura).
The author marked this model as their own original creation. Imported from Thingiverse.
