The pads on clamps can fail and need to be replaced. These scalable pads can replace them for low-force appications.

UPDATE: here are stronger clamp pads that use coins as inserts.  The ones below work for lower force applications.
------
Sometimes, clamps at the my maker space (acemakerspace.org) end up with missing pads.  These replacements are scalable so you can make one fit any clamp.  But you can only apply just so much pressure to a clamp pad before it gets destroyed.  So, I mainly use these for smaller clamps where less force is needed anyway.  

I've included PLA gcode files for a variety of scales: 100%, 110%, 120%, 130%, 140% and 150%.  I found that the 120% version fit my clamps best.

You can scale them to any size you need in the slicer.

They're designed to be printed on their side with the slot vertical.  That way they don't need any supports.  

To install, choose the size that you can't quite push on with finger pressure.  Then use the clamp itself to drive the ball end of the screw into the printed clamp pad.  It should go past a point of high force and then be completely loose.  That means the ball is inside the clamp's cavity.  The clamp pad should move freely so it can accommodate a slight angle. 

It is designed not to leave an edge mark in wood being clamped.  You could lightly sand or file the flat face and the chamfer edge around it for an even smoother clamping surface.

You could also print these in TPU, in which case you'd want to use a smaller size so it stays put.  It might not move quite as freely, but it will move easily enough for the purpose of clamping things.
