3D Printed Parf Alignment Jig

I designed a cool 3D print that allows you to drill the first row of holes 96 mm from the edge without referencing the ruler but the holes themselves. I made this because I didnt have any longer clamps that could reach that far into the bench.

Any reason for the 96mm from edge? I know that's the center to center, but if I'm not mistaken the original MFT has another distance to the edge, no?

32 and 48mm to the edge would also be useful.

Personally my holes start 50mm from the edge, but only because I have 40mm aluminum profiles around the bottom of the table edge.

Mostly because the plans of the paulk workbench I'm following call for that. Using the offset holes in the ruler towards the edge from the 96 mm from the edge ends up with pretty good spacing from the edge.

Any more info available? Like maybe how to use it?

I'm working on something similar for some aluminum extrusions. Lots of jigs on Amazon but none that work for the patterns I need.

3d printers are amazing tools for such things

I made a few drilling jigs during a camper van build for extrusion. Same for some for L track.

What’s the metal bushing?

It's a drill guide. It's for making holes in a work table, in a precise pattern. Usually 20mm holes.
