- Fix routes too close to mounting screw holes can be stripped if screw is overtightened
- PCBs v4 are not compatible with case v5, connector cutout location have been changed - Moved thumb JST connector so that it is not necessary to trim JST cable - Moved JST connectors, reset button, power switch on main PCBs such that it it easier make parametric case - Added .scad for Iceberg/Clay cases
