No only this filter printed inversely. I opened it in Makerware and it shows the right design. But when you click make and go to preview the build it shows the inverse of what should be printed. I opened it in Cura and the preview shows the correct design. So something happens to it in MakerWare i think.
Edit: Opened the STL in Slic3r and changed some settings and then exported the STL to open in Makerware and the preview looks correct now. Lets hope it prints right.
