I made this for my Craftsman table saw. It was missing a bolt that keeps the table extension in place. I printed it in ABS with 50% because that is what I had set up on the printer. I used CURA for the slicer with brim however it seems to have printed the brim offset so I had to cut some of the brim out of the top when the print was done. The threaded hole is 7mm. i could start the bolt by hand but had to finish with a screw driver. If you want to hand tighten consider making the whole slightly bigger.

In the picture the original part is black and my printed part is translucent.
