DIY CNC Machining Quadcopter Arm

Doing some machining from 6061-T6 aluminum on my diy CNC machine. The whole process includes one tool change and a user-input stop do i can fasten the part down from the inside. I can knock one of these out in about 30 minutes or so so the price should be pretty low. I would not want to go into production for these because it takes two hours for a pair of arms!
