Stands that allow you to put your PVM-14L4/PVM-14L5 (May work for 20L5 or other models and brands, but not tested) on top of an Extron Crosspoint Matrix switch.

Mine is a 8x4 RGBHV / Component switch with the small buttons. Not sure of a specific model number.

Not sure if this will work with the variants with large buttons.

I printed at 0.2mm layer height with 10% infill and it's been happily holding my monitor for a couple years now.
