  Notes
    ! Prints flat, face up, no supports — the countersinks are 45° cones. 3 walls, any infill.
    ! PETG outdoors and in damp rooms; PLA is fine indoors.
    ! Corner holes take ⌀4 countersunk screws. Tape mount: regenerate with mount=tape for an uninterrupted frame.
    ! Need bug-proofing? Glue fly screen to the back — the frame is flat on purpose.
