(Mostly) 3D Printed .0005" Indicator

I want to start by saying that I'm sharing this because some people have expressed an interest in the files. I didn't intend to share this when I had made it and as a result I really shot from the hip on the design without documenting anything and it's not going to leave an easy project for anyone to replicate. Many of the 3d printed components were sized specifically for how they'd come out on my printer, Many need to be drilled and tapped, many of the shims were required and I never made drawing for any of the machined components because I just machined them to fit at assembly.

Sorry this project is kind of a mess. I didn't take my usual methodical approach to the design and didn't think I'd end up sharing these file anywhere.

This project requires two 608 bearings, two machined bushings (8mm OD, 4mm ID, length as needed) Two M4 set screws, five M2.5x8 low profile socket head cap screws, extension spring ( https://www.mcmaster.com/9657K43/ ) and several Ø4mm rods( https://www.
