FYI how to make circles on the Juki 2010 Q

A couple posts back I made a makeshift circle maker for my Juki. I looked around to find an actual attachment made by Juki, then I looked for after market parts and was unable to find one.
I looked around at circular stitchers by other manufacturers and ordered what looked promising. Well it worked. The Singer Circular Stitcher part no. 161847. I'm still using the circular discs that I made for my makeshift one, and this one makes more uniform circles because I'm not holding the tack. Little hard to screw down because of the screws design.
