It's a printable clone of the lasercut X-carriage parts for the Rapman.

If the brittle acrylic part is starting to crack after years of abuse, why not make a new one out of printer plastic? Copied straight out of BitsFromBytes's original CAD drawings, it's an exact duplicate of the original.

I've got one on my printer already, and it's working just as well as the acrylic one did.


Out with the old, in with the new. Make sure to print it standing up to beat the warp, with infill for the center hole.

Hi Zaphod, I'm curious as to were you found those files too. I can only seem to find an old pre Rapman laser cut darwin at the SVN repo. Not the actual Rapman

ok, just now I see that that was not your answer.

Where did you get the original CAD files?

RapMan is a commercial version of the laser cut Darwin RepRap ...

... "as RepRap is a free project - the Bits From Bytes designs are all available for download so you can make your own too. You can get them ..." see http://reprap.org/wiki/BitsFromBytesRepRaphttp://reprap.org/wiki/BitsFro...

... from the source reprap sourceforge repository:

That was true in 2008, but unfortunately BfB went closed and their subsequent CAD drawings were not published. To get CAD models now requires reverse engineering.
I think this vindicates Adrian Bowyer's point, if you go closed source you end up with a developmental dead end. An Open Source Rapman could live on and evolve, but of course BfB/3DSystems don't care about that because they are not making money from it.

Gave the Rapman 3d model a proper home here: http://www.thingiverse.com/thing:463203

Happy hacking!
