The overall project is to make a robot about 75cm tall. To begin, I identified 2 types of movement for all joints (other than eyes and hands). This part of the project is for joints such as rotate movement.

For other type of movement, go to: https://www.thingiverse.com/thing:3091483

Printed parts:

• 1x Rotate-A: Servo mount
• 1x Rotate-B: Any receiving bone adapted to change as needed
• 2x Rotate-C-2X: 2 pieces receiving axle bloc
• 2x Rotate-D-2X: 2 pieces for the bearing and the rotate axle transmission
• 1x Rotate-E: Axle transmission
• 1x Rotate-F: Rotate join between axle and Servo

Non-printed parts:

• 1x SG90 servo motor
• 1x Bearing 8x12x3.5
• 10x M2.5 8mm screws
• 8x M2.5 nuts

Steps:
1- Slide the bearing onto the rotation shaft "Rotate-E". Use pliers as needed. It's tightening in order to fully utilize the functionality of the bearing.
2- Insert the rotation axis "Rotate-E" between the two parts "Rotate-C-2X"
3- Place the 4 nuts in the spaces for this purpose in the "Rotate-C-2X" parts.
4- Insert the 2 "Rotate-C-2X" parts into the "Rotate-B" section, then tighten the 4 screws.
5-Put the "Rotate-D-2X" parts around the axis and insert the 4 nuts into the "Rotate-D-2X" parts
6- Slide the "Rotate-A" part around the "Rotate-D-2X" parts, then tighten the 4 screws.
7- Cut a small white piece supplied with the servo motor to insert it into the "Rotate-F" piece
8- Place the "Rotate-F" part on the "Rotate-E" axis. These parts are not covered together
9- Place the servo motor making sure that it is inserted in the "Rotate-F" part and that the "Rotate-F" part transmits the movement to the axis of rotation.
10- Screw the servo motor into the "Rotate-A" part
