($20 donation-to-author-version) This is a version of the Open Source RepRap (technically a GPL'd RepStrap) modified to print on Ponoko's service by diamondage.co.nz and to use more frequently available components. This is designed for the experimenter and for the moment there are no build instructions beyond those already existing for Ian's original design at bitsfrombytes.com.
It includes many experimental features: 2 extruders with a manual swap mechanism, a gear motor option for the Z axis, lasercut bearing races, ball-chain throughout instead of belt, NEMA17 and NEMA23 motor mounts and some thickened parts that I found to be too breakable in 4.5mm acrylic.
The original SVG source files are available free from the RepRap Project SVN repository on sourceforge.net and you do not have to pay me $20 for them. But if you do, I get to know how many RepRaps are made from my design, which is cool. - Vik :v)
