Desk mounted speaker stands

I made a desk-mounted speaker stand for my speakers to raise my speakers to head height. I used epoxy to glue the bars to the base, and some felt pads in the base to increase the friction with the desk and reduce the vibrations. It fits my desk which is 19mm thick. If you have a desk of a different thickness, then let me know. I have uploaded STL files for desks that are 17-30mm thick.
