Wall mount to column adapter

The bike arm mounting plate attaches to an aluminum plate in three spots. I drilled and tapped the two bottom holes and the top hole for some short 6mm long M3 flathead screws. After test fitment i opted to use 'medium' strength thread-locked to keep them in place. The four perimeter screws are not tapped to allow very long machine screws to make it to the back of the clamp.
A Quick Fit-Check of the 3D Print

With the 2-part sliding clamp printed, I wanted to make sure things actually fit. At the time i had screws that were 'almost' long enough to reach thru the parts and make it to the back plate. I opted to change the design a bit to allow thumb-screws for tightening / loosening, so adjusting the height does not require a tool.
