Delicate Ring-A-Thing /w Pin Connectors Ring

I like the original Ring-A-Thing except for it's chunkiness and completely separate pin. I decided to save a little plastic and revised the design slightly to eliminate the chunkyness, save some plastic and make it a little more "delicate" for small hands.

I wish OpenScad had a filet feature.

** UPDATE ** I added a second scad file and stl. This one has a shorter peg for less plastic and less bulky charms...unfortunately the charms are incompatible with the original Pin based Ring-A-Thin
