So I just had a crazy thought… Purchase a second v2 Single Tool head, Print all the plastic parts, combine, and have a Dually for $175 ish. After some cursory research, it seems as everything will work. I’m going to have to source the screw on connector that fits the electronics housing, a few molex plugs, and 4 heat set nuts for the fans to mount into. Other then that, I should be able to scavenge everything else from the tool head that ships with the Taz, and the other single toolhead.
I’m going to look more into this this weekend. Surely someone has tried this before, right?
