Rendering STL files for Cyborg Beast fingers errors out.

But the Davids Fingers render to STL just fine.

Exactly. David's designs are all OpenSCAD, as is MakerBlock's Cyborg Beast, which render fine.

The thing I've run into is that almost all of the STLs from Blender are non-manifold (e.g. faces are inverted, vertexes don't meet properly, etc.), a flaw that causes OpenSCAD to refuse to compile them. It'll preview them just fine, which is acceptable for the demo. The old STLs that were cleaned work, but they're not the latest Cyborg Beast model.

Marc has been working on cleaning the Cyborg Beast files so that they're valid, after which this will be fine.

Alternatively, the parametric design is improving as well, so we can just use that one.

To be clear, it is a bug, but it's a but that we know about and accept until we get a fixed STL file.

Fixed with Cyborg Beast 1.4 files, which are manifold.
