It's kid of a DIY project, where you order the parts and assemble the aperture yourself to your liking. The housing is 3D printed and you can choose from three different models, all of which will work with either left or right-handed sights.
The page for this project has been added to this blog at http://archerygeek.blogspot.com/p/3d-printed-aperture.html
Feel free to make as many as you want and share the link with your buddies. It's not a money-making project for me. I'm offering it up to the archery community to do with what they wish. 3D printing is supposed to be that next "disruptive technology", so disrupt away!
