I think it is called "make it yourself". It really is only a sturdy shelf to minimize vibrations that is set at a measured level below the cabinet surface so the machine will be at the same height as the surface of the cabinet.
I don't know if you can even purchase the adjustable hydraulic attachment like the ones in commercial cabinets.
You could even install those bookcase shelving attachments that have adjustable pegs so you ca move a shelf up or down and put a nice thick board on it for your shelf.
Good luck and post with updates. Lots of interest here.
