My flexible Touring Pi mounting base
Here is a simple 20x20mm aluminum extrusion carrier base, with some AliExpress standoff mounting brackets for the MiniITX board. An aluminum mesh provided protection against falling screwdrivers and such (when on or near the desk).
Pricewise between a Dimas Tech (cheaper than my solution!) and an openbenchtable. But who knows how this evolves.
For the moment I am happy that about every other month I seem to got hold of another CM4.
How are you mounting your TuringPi?
