The only parts I printed with supports were the "gripper servo segment" and "gripper mount to MG90S" the rest of the parts all printed fine without them.
All the bolts are M3 (3mm diameter) button/rounded head. (The number of nuts and bolts doesn't match because some bolts are screwed directly into the plastic or servos.)
9x square nuts (M3)
13x hex nyloc (M3)
Various sized screws for the servos to hold them in place and attach parts to the servo arms.
3x HJS3315D Robot Servo
2x MG90S TowerPro Metal Gear Servo (Interchangeable with SG90 TowerPro Servo as they are nearly exactly the same size).
1x SG90 TowerPro Servo
It is controlled by an Arduino Uno and 16-Channel 12-bit PWM/Servo Driver I2C board.
The Arduino code is available on my GitHub but will need some edits to work with your arm correctly (Read the code header and check the TODO's). https://www.github.com/isaac879/3D-Printed-5-Aixs-Robot-Arm
