I needed a way to mount axiiio nano Motion Pancakes to flat surfaces, and this is my solution. The clamp has a central hole for cabling as well.
There are 4 inserts that I heat using a soldering iron, so they melt into the plastic. The M3 screws are screwed into the inserts so that the locking mechanism can clamp the motion pancake to the base. The base is anchored to the surface however you like.
Here's an animation of how it works:
I'll use this to complete a skateboard dolly rig project:
I've published the completed skateboard dolly rig project as well.
