Here's a very rough estimate. This is how long it'd take for someone who's familiar with the steps. E.g. if you've never tried soldering, it could take much longer. - Days/weeks of waiting for components to arrive. (: - ~20 hours of 3d printing - 1 hour of soldering - 4 hours of cable assembly (worst part) (: - 4 hours of assembly - 4 hours of installing software
