No Twist Clamp Pad

This is an adaption of a simple upgrade I saw John Heisz do in this video: https://www.youtube.com/watch?v=f_kCk3M8vyc

This model fits the harbor freight f-style clamp. The dimensions on John's clamps are a little different, but I used the general overall thicknesses which are roughly the same thickness as the OEM plastic cap that covers the clamp pad.

In his words
"These do three things:
1 - Keep the clamp pad from marking the wood
2 - keeps the pad straighter, so that applies the pressure more evenly
3 - keeps the clamp pad from twisting the work when you tighten it."

I've included the Fusion360 file so you all can remix the file to fit your own clamps.

There are currently two sizes based on the two diameters I've found for the metal pads at the end of the hand screw (again, harbor freight). Measure yours before selecting and printing - I'm happy to make tweaks and upload new models, so just ask.

Current uploaded pad diameters include:
0.75in (19.05mm)
0.795in (
