ZMR Reinforced Arm

For ZMR 250 ARM drone kits. You'll be surprised how much stiffer this arm is with the bump.

I rounded some of the edges and added a bar in the middle to make the part flex less and it doubles as little landing feet. It does increase the weight by a little bit but it's only about 2 grams.

Print with the bump facing up and then install the arm with the bump facing the ground. Recommend printing at 100% infill.
