The enhanced wing features a taller belt height and taller claw grip to really push the pistol grip into, or around, or waist.
The design prints in two parts (wing and locking peg) so the wing itself can print flat. The locking peg is inserted into the wing and is retained by the stock screw. The picture does not show this well, however, since I originally made the peg too short so the screw did not fully retain it. This has been fixed in the released STL. I've also since rounded out the bottom so it does not stab your groin or thigh and included a skinnier version of the wing if that works better for you.
Recommended to print in PETG as PLA can warp and bend on a hot day.
