Tell us about yourself!
I don't see why there wouldn't be interest, it's an innovative design and personally I'd like to see how you worked out any stability problems. Right now I'm working off a Prusa i3 with two z-axis motors. If I could get rid of one of them and still have it be level, that would be sweet. Seriously, I'm not trying to enforce by-laws or anything, I just wish you'd posted your parts so we could print them for ourselves. Also, any issues you ran into.
Agreed. I also can appreciate the simplicity of this design but you have provided no actual instruction. Hardly appropriate for a site called 'instructables'.
