The Tevo Tarantula do you think they used Openbuilds parts? I saw their wheels and they didn't look like the ones from the parts store here. I also wonder if we sourced all of the mechanical parts only (extrusion, wheels, etc...) would it be cheaper than that printer? If we take away the electrical parts that is around 75 less. HBP around 20 for a MK3, the four motors of about 15 a piece that makes the hardware around 70-80 dollars. I wonder if we could get all of that hardware for that price, or less, directly through Openbuilds?
