I've searched in the usual places: Grabcad, 3D Content Central, Traceparts.
I don't want to model it myself if someone has already done it. STP, IGS, X_T, SLDPRT, pretty much anything 3D will do.
I just need an outline. I want to include the outline of the drill in my models of levelling anchors, so we don't end up with welded frames that we have to remove before we can drill their mounting holes.
