I think if you are going to print one of these for shop use, I would make sure you increase the infill. I printed mine with 3 perimeters and 4 layers on top and bottom, with only a 25% infill. It makes for a very lightweight version, especially if you are using a cheap Chinese digital dial indicator. I am not sure that for a tool like this you need to buy an expensive Japanese or US made dial indicator. Even buying everything from HomeDepot or Lowes and Harbor Freight (for dial Indicator with a 20% off coupon) you would be hard pressed to spend more than $30 on this tool in total.

I also included STEP and F3D files of the 3D source, specifically for people that want to modify the design in any way. STEP will import into most 3D CAD applications and F3D is a direct Autodesk Fusion 360 file.

Note: I printed mine with no supports, there aren't many sections with large overhangs (only the nut recesses) so bridging is very easy for most printers.
