Wings 3D is a subdivision 3D modeler inspired by Nendo and Mirai from Izware. Available on Mac PC & Linux it is possible to assign materials, vertex color, UV coordinates and textures but no animation yet.

The site has a useful forum with tips & tutes, gripes and grumbles, links, release announcements etc. etc. the development is through SourceForge, so you can track the bugs, download & submit code.

Wings 3D imports:

Nendo (NDO)
3D Studio (3DS)
Wavefront (OBJ)
FBX (on Windows and Mac OS X)

With this kind of software you could import your 2d illustrator files, extrude and assemble a 3d object to prototype your Ponoko creation like John’s Stiletto Laptop Stand.

Think of it as a virtual version of measure twice cut once.
