Hand Controller v3 PCB ready for fab

I have the board for the Hand Controller designed. Need to add the Light Sensor Box and a shield for the Mega. Passes tests for manufacturing at Bay Area Circuits where I can get a 50sq.in. made for $30.

I want to panel a single board to get at least 2 hand controllers, 2 light sensor box boards and the Mega shield on it. My plan in once all three designs work to do an ugly merge in fritzing and lay them out as one piece that I’ll cut down after delivery.
