About this 3D model

here's the second in a Babylon 5 series of pins Dr. Fraser's med badge this actually came out of the B5 wingding typeface along with some others I'll try to post soon. it take a bit of work to make them printable but the customize stencil app helps a lot as always any comments plus or minus greatly appreciated! ( how am I going to know if I screwed up or not if no one tells me?)
