Eurorack 3U Rail End Bracket
This L-shaped side bracket turns a plywood box into a Eurorack 3U case. Its two vertical 5.5 × 16 mm slots are 122.5 mm apart, matching the 3U panel hole pitch, and they take an M4 or M5 rail-end screw with ±5 mm of adjustment, so different rail profiles still line up. You screw it to the case floor and side with #8 wood screws (4.8 mm holes). It is 155 mm tall and 30 mm deep, and it prints lying on its L profile so rail loads run along the layers.
