I hate supports. I try to make all of my designs print without supports.
I also do not like pegboard models with plastic pegs that easily break. I prefer to use metal pieces from Harbor Freight Tools https://www.harborfreight.com/pack-of-7-1-1-2-half-inch-angled-pegboard-hooks-65474.html with my models since they only cost $1.79 for 7 hooks and they are MUCH more durable.
This DeWalt 20V Max battery rack holds 2 batteries. They are designed to multiples fit side-by-side on a standard 1/4" pegboard with 1" between holes. For the newer, larger DeWalt batteries, you need to use the single holders.
The metal pegs need to be trimmed down to fit flush (remove about 5-10 mm off the ends).
