Model of the traxxas villain gearbox (step and stl) with the new style flanges on it. I did not draw the metal plate that comes with the new style mounts (instead drew the old style interface) but the mount points are there.
there are 4 files. two are for the old style mount with the new style stiffening ears. the other two have a gaping cutout to clear the new style mount's standard metal plate. cutout is not exactly the same as on the real traxxas parts but it is a clearance feature anyways so it just has to miss the fastener holes.
