2020 aluminium Robotic Arm swivel base with nema 17

This is the base for the robotic arm which has a nema 17 motor to rotate the whole arm. This requires M5 bolts to attach the 2020 aluminium and M3 bolts to attach the motor to the base. it will require support material as it is to be printed out in a single print and there are overhangs above where the motor attaches. This is a work in progress piece as I am not happy about how the two plates are attached to the base. This version doesn't use as much material.
