Makita 18v battery rack - multiple

I liked the https://www.printables.com/model/318792-makita-18v-battery-holder-3screw model but wanted to hold more than one at a time and also save screws ;) IDK if it's a “remix” because I modeled it from scratch -- the tolerances are a little different and there's no bottom fillet to worry about, plus the battery “rail” has some chamfers for easier slotting in. Unfortunately, the 4x version is too big for a mk4! Print with supports . “snug” worked great.
