I downloaded and printed namomo’s G2s digital indicator mount (http://www.thingiverse.com/thing:1381109). Only to discover that his indicator (though it looks exactly like mine less the HFT house brand “Pittsburgh©” on the face) is critically different dimensionally. I didn’t see another one with the necessary dimensions, so I modeled this one up and printed it. This was my first time using a slicer program and I couldn’t get it not to go overboard with the support material where I was going to slip in a nut, so I just tapped the holes instead.
Notes, the mounting plate on the back of the indicator needs to be removed and remounted 90 degrees to how it comes out of the box (four small Philips head screws), but it is no problem.
