I am collecting parts for a DIY 3D printer and am ready to pick a frame. I already have 5 Nema 17 stepper motors, an arduino mega 2650, a ramps 1.4, and a E3D V6. I need a frame and extruder for somewhere around 7" x 7" x 7" build volume or greater.

I am looking at the Mendelmax 1.5 RepRap kit but that is just the plastics. If the hardware isn't too difficult to find then that could be a good option.

Any other's I should be looking at?

Thanks!
