About this 3D model

Mashup of Johann Rocholl's latest carriage for his new printable recirculating bearings, with pierre2339's modification for open belts. A friend has now tested and reported that it's working fine. My fork on Github: https://github.com/mkeveney/kossel For more on the bearings, see Johann's page: http://deltabot.tumblr.com/ and his Git repo: https://github.com/jcrocholl/recirculating
