This is the entire deprecated Bits from Bytes Rapman (except extruder) as one 3d OBJ file. I ripped it from the 3d PDF years ago using 3D Ripper DX. Those rips are never 1:1, they lack proper scaling and are skewed so I had to de-skew and rescale to original dimensions based on measurements on the machine. So don't expect 100% perfection, but I managed to get it extremely close to what it should be and so far haven't found any issues when using this as a basis for designing new parts or extracting exciting parts. Every part is a separate object so you can easily extract only what you need. You can also use the 3d files to extract 2d profiles for laser cutting.
Please not that the content of that PDF is most certainly copyright protected as it was never released under some CC or open source license... (Although it should have been as it is a derivative of the RepRap Darwin design). So it's your own responsibility if you use it. I only release this since the machine is deprecated and neither Bits from Bytes nor its parent 3D Systems produce or support this machine anymore. I hope this file can extend the life of all the Rapman machines still around.
If you extract or remodel parts based on this file, please add them as a remix or derivative of this Thing so people can discover them easily.
