Beefy Tricopter Yaw

thingiverse

This is a reinforced tricopter yaw mechanism that has been upgraded to provide added strength and stability. Previous designs were found lacking due to the small size of some components, so they have been modified to enhance durability. To prevent damage from crashes, stoppers have been added to the top boom holder to limit servo movement to 45 degrees in each direction. This should help avoid stripping out the servo motor. Instead, the top and bottom parts will separate if connected with zip ties, hopefully breaking at these weak points rather than elsewhere. Trials will determine whether further reinforcement is needed. The design has been optimized to minimize the need for supports during printing, provided the parts are correctly oriented. The mechanism has been tailored for 15mm carbon fiber booms but may require adjustments based on personal printer settings. As of now, it's unclear how well it will fit these specific booms, and further testing is required to ensure a proper fit. A key feature of this design is the absence of holes in the top and bottom parts, making them easier to print without supports. These holes can be drilled out later if necessary. The center hole is 6mm in diameter, accommodating bearings or similar materials for pivot shafts. A Fusion 360 file has been included for anyone who needs to make modifications to these parts. The mechanism is designed specifically for motors with a 19mm hole pattern.
