About this 3D model

This has been a project that I have been thinking about for over a year now. I wanna make a mobile small scale 3d printer. It usese a ulitmaker style gantry modeled by Chris Spawn in Sketchup -my goal is to have a working protoype at the end of september -I would love to have this run off solar power in the distant future -it uses stepper motors to drive the wheels as well the XZY/E functions -This is a work in progress posted 8/28/20
