I'm trying to print this small piece (h x w x d) 9 x 53 x 14mm and got the following auto error message: "Your model was too small for any of our 3D Printers. Our printers have a minimum bounding box size (h x w x d) of 0.25 x 0.25 x 0.25 cm / 0.098 x 0.098 x 0.098 inches. Don't fret, we have a tutorial explaining how you can scale your product: http://www.shapeways.com/tutorials/converting-with-accutrans -3d." This is a very small piece but I've printed other very small pieces before and not run into this error so I'm not sure what I'm doing wrong. Intended material is bronze. I triple checked the SW file and the units are all mm to 4 decimals. Is it just a matter of thickening up the spindly clip portion of the design?
