PrintrBot Jr. v1 Y-Axis remake

This is a remake using the diagram of the original wooden parts for the Printrbot Jr. v1. I merged some parts and converted others to form a much sleeker and lighter profile.

Important Note:
The extruder platform is for the new aluminum extruder BUT I have included the .skp files if you want to modify them.

More to come in my personal journey to re-create my entire Jr. v1 in plastic! (all the wooden parts anyway :P)
