I made the attached STL files but they are being listed as non-printable (during pre-flight for Cube 3) on cubify.com. I tried repairing the file to the same result. I used 123D but not sure what is wrong with them (so I can learn and fix) any help would be appreciated. I have a 3D Systems Cube 3 Printer.


Thanks
