HAAS CNC Machined. Was actually quite easy to do with Mastercam. Took about a half hour to set up and a half hour to run (slow program). Not too bad, lots of weight saved and tons of strength retained.
COME SEE IT AT THE LOS ANGELES REGIONAL!

its not the panel to cover the circuit breaker is it?
sorry couldn’t resist…
