Brook Drumm created the wonderful original which is far more rigid and can print much better then most of you would think. It is a great design with small overall dimension but for all that with a big print area. This is the reason that there are a lot of derivates. Thank you very much Brook for that genius idea.
My intention was to be as close as possible to the original parts but with a lot improvements.
Here is one of my first prints: http://www.youtube.com/watch?v=lmT9ujijztQ
