No Twist Clamp Pad

This is an adaptation 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 perfectly, utilizing its dimensions which are roughly the same thickness as the OEM plastic cap that covers the clamp pad. According to John's words: These upgrades accomplish three crucial tasks: 1. They prevent the clamp pad from marking the wood. 2. They keep the pad straighter, applying pressure more evenly. 3. They prevent the clamp pad from twisting the work when tightened. I've included the Fusion360 file so you can remix it to fit your own clamps. Currently, there are two sizes available based on the diameters I found for the metal pads at the end of the hand screw (harbor freight). Measure yours before selecting and printing - I'm happy to make tweaks and upload new models if needed. Available pad diameters include: 0.75in 0.795in
