This mini racing drone can be 3D printed, CNCd, or laser cut. If possible, I highly suggest a CNC cut method out of 4-5mm carbon fiber sheets for maximum strength and durability. If you're looking for a super inexpensive method of producing this frame, I suggest laser cutting it out of a few layers of 1/8"-1/4" plywood glued together. I laser cut it out of acrylic as that's what it looked the best in, but acrylic is definitely not the strongest material choice as it's super brittle.
