Im a beginner too (in CAD modelling). I imagine the workflow something
you model it, I print it. Then I post pictures of the print, how is it
looks like on the
freerunner, where are the design faults, and printing faults.
Then we fix it, and print again. And again, and again.
As far as modelling is concerned, this is the open source toolbox:
Inkscape is great for the logo for example (import it into blender,
extrude it, etc).
qcad +openscad is great for accurate modelling. qcad for 2d, openscad for
3d (extruding 2d, boolean it, etc).

As arne have asked too, I own a reprap machine. So there are some limitations,
- the printing process is achieved layer-by-layer printing. About 0.5mm layers,
so you can feel them with your nail. At least 2 layers required to
really bond together.
- some postprocessing is required, polishing the plastic, to get rid
of the layers,
and have a better look
- no overhangs less then 45 degree. (ie. I cant print a standing
letter T because,
there is nothing under the top part of the T. Or the roof of the
house. (ie. four walls
plus the roof).
So summing up, we need at least 2mm thickness. So printing out the original
case is impossible, because it has less then 1mm of wall thickness.
But for prototyping, or having a gamepad, what you posted does not impose
such a strict limitation. So nobody really care if it is 3mm or 5mm thick.
Here is a picture to get an idea about printing quality (I printed an
station for my friend):
Btw I also plan to design a docking station. Anyone interested to

Ok we arrange it somehow.
