Large lock-pick handle (designed for Sparrows picks)

I have large hands and I find large handles easier to manage(XL glove size). I started out with designing a handle for wiper blade inserts, but now that I have purchased some sparrow picks, I modified my design to fit them. This handle is designed to be printed in two halves, then glued together with epoxy. It has gone through several revisions. I started by forming a comfortable handle with moldable plastic to my hands. I drew up the first version and it became my favorite pick. For this version I slimmed it down slightly. I have intentionally left the corners un-rounded and allowed the circles to stretch past the edges in order to add a better tactile feel to them (you can tell their orientation by touch alone). I plan to also try dipping these in plasti-dip once assembled, but they seem comfortable enough the way they are. Please feel free to modify as I have included the original Sketchup file. I don't have time to make custom adjustments for people.
