Makita DC18SH charger wall mounts.

You need at least two of these, three to be extra sure. Print your preferred moderately structural settings. I used 5 walls, top, bottom, 20% infill. The mounting holes are 4.5mm, the mounting pins are 8.1mm for a slight interference fit. The Mounting pins are 159mm apart. This is not a remix. I did my own takeoffs.
