This mornings project: In my ever ongoing quest to find new work holding options, I found some Youtube videos that show wooden cam clamps but there wasn’t a design file easily available. So I decided to copy the idea but design my own from scratch. And of course share the design file here for anyone who wants them or wants to modify to your own purposes.
The holes are .257" in diameter which provides a good fit for the 1/4"-20 bolts I use in my threaded inserts (but you could also use 1/4" dowels as well). My wasteboard has inserts in a 2" grid pattern, so I put enough holes in the clamps to avoid any dead space where they might not reach. Made in White Oak which should be suitably strong. The finish isn’t very good because I had to stop and restart the project after adjusting work holding, resulting in a slightly different zero in the middle of things.

The .STL for those who don’t use Fusion (but this is the first time I’ve exported as an .STL, so not sure if that works well for importing):
