A pair of side clamps meant for holding100 x 100 mm stock from the top and side.

The pocket and slot for the bolt hole in the block part is optional, but adding a bolt there after tightening the cam provides some extra security. The blocks are sized so that there should be bolt holes in the right places when using 100 x 100 mm stock with the anchor. Since this is optional, other mounting holes should let this work with other sized stock as well.

The engraving is also optional, and I encourage you to replace or add to it. I used the "trace 3d contour" feature on https://www.printables.com/model/443929-clamps-futurama-wall-art for the ones in the cover photos.

The holes in the lever are technically optional, but they let you use the 4th axis chuck wrench or a screwdriver to get some extra leverage.

There is a small counterbore on the opposite side of the bushing, but it's very optional, so I didn't include a two-sided setup here.

I was inspired by https://makerworld.com/en/models/1071926-quickcam-bench-dog-blade, but I designed this from scratch. Here's the onshape doc if you want to fork it: https://cad.onshape.com/documents/fa2650e88ff711d86bb1f74b/w/9ab80054f74ba2a4d9a617bc/e/65d48e00d20f691353233353.

Warning: I have not tested the exact uploaded .nc or .mks files, as I was doing individual parts while developing it, and now I'm out of the right sized stock. If you want to use tabs or double sided tape instead of securing mid-job, you can definitely arrange things more optimally.
