Driveway Marker Clip

This is a multi purpose thing. I designed it to be able to attach orange driveway marker posts (roughly **1/4" diameter rod**, with reflective tape at the top - commonly found at least in the northern USA for $1-$3 in winter, sometimes year-round) to things that aren't driveways, to mark corners. However, you can use it for just about anything of similar shape and size (and if you're ok modifying one number in the CAD, you can adapt the diameter to suit other sizes too).

Unlike similar store-bought clips, this snaps on to the pole (rather than clamping), and has a square hole for a carriage bolt instead of just a screw hole. The design is for a **5/16" carriage bolt** because that's what I had the right kind of, but you can adjust the cad for a different size if you know the dimensions of the square part.

If you want to edit this to use different sized things, please see the "How I Designed This" below - I walk through each step of the design you might edit to change simple dimen
