A remix of a case by Duglum, reworked for ESP-KVM by @Pnwcomputers (#83). Neither board needs screws. The P4 board snaps onto edge rails, and the C790 snaps onto ledges above it, with stops behind it so an HDMI plug can't push it back. Pinholes on both sides reach the Reset and Boot buttons with a paperclip.
Version 3.6 adds an opening for a USB-C panel socket above the Ethernet port, for power. The lid takes four M3x10 screws and M3 square nuts (DIN 562). It prints in PETG at 0.2 mm, with supports only under the port openings.
