I purchased a WEN 1" dial indicator from Amazon:

My guess is that this is similar to a Harbor Freight caliper. The back measures 53.25mm. Many backs for dial gauges come with a little tab so that you can mount the calipers. I needed mine flat, so I made one!
Not that it matters, but Thingiverse does not let you specify the Ender 3 V2, which is what I printed this with.
