I built a new studio desk based on the Platform Desk by Output. It has a monitor shelf, rack space for audio gear, and a sliding keyboard tray, with all plywood construction. I drafted the cutout plans in QCAD and then produced a tutorial video.
The complete cutout plans for this desk are available on my Patreon page, and have been built and tested by makers and builders around the world. They are available in a slightly modified version which uses only 2 sheets of plywood, or a full-size, fully-accurate reproduction which requires 3 sheets of plywood.
