The OUAGO, made for the optics head of the Elmar 90/4, is a focusing helicoid for M33/0.75 threads to Leica M-mount. This print is to provide it with a follow focus gear, for video. (I use it with a M4/3rds M-mount adapter & BMPCC4k). It is a tight fit, printed FDM @ .2mm layers. There is a chamfer on the rear to help fit it more easily, but you may still need to sand it smooth. Gear is the standard 'movie' 0.8 pitch. and 8mm thick, mounting contact area is 6mm wide (though the OUAGO grip is about 5mm wide).
