ATTENTION!!! Please ensure this design has been thoroughly tested on a rocket before launch to guarantee a safe and successful ascent. A static fire test is highly recommended to confirm everything is functioning properly. If you encounter any issues or believe the TVC Mount requires improvement, please don't hesitate to share your concerns. Good luck with your project and welcome to the GyroMk02 community! This design was inspired by Joe Barnard from BPS.space (https://www.youtube.com/channel/UCILl8ozWuxnFYXIe2svjHhg). To build it, you'll need two push rods, screws that come with your servo motor, and eight M3.5 or M4 screws (choose M4 if your 3D printer isn't precise and M3.5 if it is). The length of the screws should be around 8mm or slightly longer (12mm). You can use the Mg90s servo (recommended) or the sg90. Both axes have at least 5 degrees of freedom in both directions. If you plan to use this on a rocket, make sure to perform an estatic fire test first! If you're unsure about anything, please refer to the images above for clarification. The Gyro Mk02 was designed to fit airframes of 74 mm, but keep in mind that the servos might get in the way, so some cuts will be necessary. Please note that the angles of freedom are different for each axis and direction. Make sure you consider this before programming your TVC mount.

The X-axis pushrod slot is now in line with the servo arm, improving the TVC mount's precision and safety. Update 11/05/2019 After receiving great suggestions, I've created a new outer gimbal version where the distance between the servo arms and pushrod slots is the same for both axes. This improves the TVC mount's precision and safety. You can choose to print either version. The new design also features smoother curves along the side and is slightly thinner. Update 17/06/2019 We've reached over 500 downloads! I'd like to thank each of you who trusted my design, and I wish good luck to every rocketeer out there. To celebrate this milestone, I'm counting on your help to create a special 500th version of the mount. Please leave suggestions below for improvements or ideas that could make it look even better. Update 09/09/2019 I'd like to apologize to anyone who may have spent money buying screws only to find out they weren't the right size. I've corrected my mistake above, and you can use M3, M3.5, or M4 screws (choose M4 if your 3D printer isn't precise and M3.5 if it is). Sorry for any inconvenience this may have caused.
