I've remixed @eaglesemnt_1407405 design for a SKÅDIS T-Nut Makita Charger mount. (Tested on my DC18SD model)

My version is it's designed to utilize the existing screws on the charger for mounting, offering a solutions for those who do not have other screws to suit.

While this adaptation has resulted in slightly narrower mounting posts to accommodate the charger's screws, I've compensated by lengthening these posts to improve fit and strength. I also used PETG to help with strength.

It seems to be holding up well under regular use.

For installation, you will also want to print 4 x m2.5 T-Nuts and 4 x m2.5 guides (link: https://www.printables.com/model/228663-skadis-t-nuts-mounting-system-for-ikea-skadis-pegb).

Heartfelt gratitude to @eaglesemnt_1407405 for his mount design and @6d6178 for the SKÅDIS T-Nuts system.
