3D printable robotic arm

Technically mk3 of internal development, but for y'all it will be mk1.

Feel free to remix/change as there are some things that are a bit iffy in relation to weight management and gripping things but other than that it works well.
This is less of a utility robotic arm but rather a more "fun" one.

This only contains stuff for the robotic arm, no rover, as that is a WIP(and will be for a while as I've taken a break).

Components:
6 MG995 style servo motor (other versions work too, also for my build I specifically used 5x 180 MG995 and a 360 free spin MG995 for the base)
Lots of M4 screws and nuts of varying length, (Bare minimum: 4 each per motor and 10 for the claw mechanism)
The small screws included with the servo motor (3 per motor)
A microcontroller or something to control the servos. (Personally, I used an Arduino Uno)
(HC05 Bluetooth module if you want)
