I've modified my Sculpfun S6 Pro and I wanted a better electronics enclosure. This enclosure uses a front plate to better access the board. The case accommodates the MKS V1.0 board that came standard with the laser.
Additionally, I added a 40mm fan to the front plate; 5v fan that plugs directly into the extra 5v connector on the board. The fan is mounted to push air directly onto the board and exhaust to the left.
This can probably fit the Sculpfun S9 (I think it uses the same electronics and mounting).
