Heh heh, this is going to be the control panel for the rocket:
I wanted this thing to look the part, so I’ve got a toggle switch with a flip up cover to “arm” it, and the mandatory big red button to fire. The toggle switch at the bottom left will be for the pump, and the key switch at top left will limit the maximum pressure. The big black hole in the middle is for a display, yet to be fitted.
The case is made of black ABS with a brushed aluminium front panel. The front panel is fairly thin (about 1mm) and was drilled using a step drill, including the large 32mm hole in the centre.
The switches make a very satisfying clunk when toggled!
