Another Dial Indicator Tool for Makerbot Replicator 2 (SCAD)

I got sick of dealing with the nearly-useless bed leveling method recommended by the manufacturer. I know I'm a decade late to the bandwagon, but I've only had this machine for a year.

I looked for a tool, and I saw a bunch of existing ones that are either simplistic or overcomplicated, but few that I had any confidence would actually fit, print,or work well. Not all indicators are the same. Posting a non-adjustable design in STL with no specified dimensions and saying "make sure it fits your indicator" makes your design go straight in the trash. Either state the one thing it specifically fits, or make it configurable. I also have zero faith in a magical press-fit design. I'm not inclined to permanently dedicate my Starrett to the printer. Either it clamps onto the indicator, or it's a single-use bad idea. I just gave up on the drift of existing designs and made my own, because of course that's what I have to do.

This design is done in SCAD. As given, it fits a 3/8" stem
