It's a tight fit, but it will go over the wire loop, and screw in with the provided screws. As usual for me, both original and Netfabbed STL's are available. Has been tested (only a little so far), and uses the clip geometry from Dan's design. (http://repables.com/r/708/). A concern is that it seems to hold it fairly loosely. I may add a little pillar for a second clip location.

Print, then ream screw holes with 1/8th IN drill bit. Remove groove mount from printer. Loosen all 3 mounting screws for lock ring, completely removing two, along the counter-clockwise side of the wire loop. Restart the two screws, and then tighten. Bend Berd-air to needed dimensions, then slip into clip. Re-install groove mount onto effector.
