Making first TVC Mount (5) – Printing outer gimbal and smoothening

The next file that I will 3D print is the outer gimbal. This is where the thrust component perpendicular to the inner gimbal is controlled.

Printing outer gimbal

After printing out the outer gimbal, I realized that the parts do not fit smoothly together due to the slight uncertainties of 3D printing (and mostly because Ender 3 pro is not exactly the best printer). Thus, I took each part and smoothened their surface with an electronic drill/grinder.

Interaction between the main body and the inner gimbal after smoothening

How the three printed out parts (main body, inner gimbal, and outer gimbal) looks after smoothening. Now, they fit quite smoothly with each other.
