A reprap inspired CoreXY printer, designed from scratch for best footprint/volume utilization, cost and print speed. Print volume ~ 209x220x273mm. Uses many printed parts, and cheap off the shelf components. Costs around $300 to build including electronics, perfect for people looking to get into 3D printing. First prototype built and running, as seen in the pictures and video. Will update with instructions on printing parts.
