This is a simple drill press square using dial gauge indicator for your drill press table

I made it in an attempt to get my old Craftsman drill press something like square with parts I had on hand. Which were, in this case, a 3D Printer, a (digital) dial indicator in the dimensions of the Harbor Freight model, and some 1/2" round steel bar stock.

I couldn't find anything fitting the bill for this on Thingiverse already. If there is post up a link!

Also, I may make an even simpler tool that uses a long 1/4" bolt with a printed part to keep it 40 degrees angled off the half inch round bar stock (which you then rotate to find square) if anyone's interested.

How I Designed This

Sketchup, in this case, although you could use anything you're comfortable with that'll produce the through-holes reliably.
