While this is cool, there are definitely cons. Range, the need for welds due to the printers having too small build size, lack of cargo capacity, and using chain drive rather than motors in the wheels/direct drive increases loss of efficiency and complexity.

Wish they'd release the build files so that folks could adapt the design and improve it.

Thanks for the inputs. I really don't know much about the mechanical things. Releasing the build files would be great.
