For those using sketchup to model items for 3D printing via Shapeways.com, this file contains the bounding boxes or printer dimensions for all the common plastic options. I haven't included the boxes for non plastics such as Alumide or Sandstone, however as I don't use those.
The boxes are on a separate layer and are labled accordingly. Just use this file for setting up your print layout and you won't have to worry about what materials will work for your items. #3d_printing #shapeways #Shapewayscom
