I'm looking to get the Jurassic Park T-Rex arm metal fabricated. I am barely good enough to create an STL model of the arm in SketchUp. I had it 3d printed, and the arm immediately broke with the tension of the spring. The metal fabrication place I talked to won't touch it without the STEP file, which I have no idea how to do. I can provide a copy of the STL file to anyone who thinks they might be able to help.
FYI, I'm not trying to make this to re-sell. If I can get this created, I'll provide the details to people who might need it. I bought a re-import game that was missing quite a few parts and this is the last piece I need to make a fully working game.
