NOTE: Dimensions were "roughly" measured. Please allow 1 to 5 mm margin of error.
I was checking the underside of my 3D printer and made some measurements of the major components. I was thinking that I may need this sometime in the future if I decide to upgrade the motherboard to a more capable mainboard.
I just thought I'd share this to anyone interested. Dimensions may or may not be similar to a wanhao duplicator I3 plus.
