The original design was great but the size was a little too large for some tastes.
These were cleaned up in netfab, scaled 65% (x and y) and the hanger was adjusted back to the original size. Based on the STL since I don't have solid works.
These printed fine on my ToM at this size with 100% fill and zero shells.
