These simple inserts go over standard FESTOOL clamps to reduce the appearance of dents when using the clamps directly on wooden surfaces. The STL file labeled as "with Supports" is slightly longer with tapered supports to enable your FESTOOL clamp to sit straight up and down, which is helpful for some clamping applications. I also tightened up the tolerances slightly with this file so its a little tighter fit. Adjust as you like.Print, insert, enjoy.
