About this 3D model

This is still a work in progress so be kind :)Ive wanted to make one of these for a long time and finally got around to modeling it and printing. The model was printed at 1:4 on a ProJet SD 3000. I am not sure how it will come out on other machines but it looks good coming from the ProJet. Just a warning the "claws" are very fragile so be careful and print a few extra!This is my first attempt so there will be changes in the near future:-Claws are too thin, need to beef them up a bit-Add built in battery compartment for LED lighting :)-Work on spring mechanism for claws-???The STEP file is available here ( http://grabcad.com/library/portal-gun ). If you would like the SolidWorks model send me an email.Enjoy!https://picasaweb.google.com/bruins.scott/PortalGun?feat=directlink
