The design was developed for use in aerospace engineering. To correct the trajectory of a satellite, several static thrusters are required. In space you don’t want to use a lot of moving parts, as these can wear over time and likely need some form of lubrication. Multiple thrusters also require many parts to function. By creating a single part pointing mechanism that is strong enough to support a thruster, but that can be operated using relatively small electric motors, the possibility of failure is greatly reduced while the number of thrusters required is diminished.
This demonstration version was printed in PLA. The original design is slightly different (especially the springs are thinner) and it was printed in titanium.
