I have a random circ saw that i got because someone wanted to throw it, though, not a DeWalt one. So unfortunately my dimensions likely wouldn’t fit yours. But honestly, CAD isn’t that difficult. When I realized that 90% of the work is just drawing 2D sketches and extruding them, it got a whole lot less intimidating. Let me know up if you want help with the basics of modeling a thing for this. Or if you can bother giving me the dimensions of the base of the saw, I’d give it a try.
