Here I made a fancy PCB holder clamp that helps keeping those little boards from moving everywhere when soldering.

It has a hollow base to be filled in to add weight and make it more stable.

You can also use it to hide some valuable goods in it from prying eyes.

Notes:

The mid-frame screws into the base left-handed, opposite to what is normal, while the top clamp normally.

I added two versions: two color and single color, no AMS needed.

Printed without any issue, but ensure clean surface.
