ZMR250 Orientation stick

I struggle to distinguish between the front and back of my quads while they're in mid-air, making them look identical to me. To resolve this issue, I attach a ball to the front of each quad for better orientation. I've designed several components that can be combined to create an "orientation device." This requires M3 screws and a tube with a diameter of approximately 3.5 mm. To make the tube, I used multiple shrink tubes shrunk onto one another and inserted them into a soda straw. The smooth surface of the straw allows for effortless sliding into the holders, making it easier to use alternative materials like glass fiber or carbon fiber rods. Fortunately, no modifications are needed to the ZMR frame; I simply utilize the existing holes. When transporting my quads, I push the rod backward to prevent damage during transit. During flight, the rod is fully extended.
