Robotic Arm V2

This is an upgraded version of the arm that I will use to build my robot army. It has a more rigid structure with bearings at each joint to remove stress from the servos.

This is meant to be used with my upgraded [gripper](https://www.thingiverse.com/thing:5477473).

Update: 1/30/23
Redesigned bevel gears to reduce slipping.

Update: 3/1/23

Update: 3/11/23
