Filament Guide - Sidewinder X4 Pro/Plus

**Update: I redesigned the whole arm & pulley using FreeCAD**
Changes:
- pulley is bigger and lighter
- arm is longer to accommodate the bigger pulley
- filament sensor mount is now offset from the arm to be straight down from the pulley exist
- no need for nuts anymore, M3 screws tap directly into the plastic
- optional small arm in the back, to redirect filament to the sides

Printed in PLA, with supports.
My slicer was trying to add support inside the small slot at the back of the main arm. It's useless, so I added a support blocker there.

**L-Arm & Pulley**
- there is a small L shaped arm and smaller pulley, that can be slotted in the back of the main arm.
- the purpose is to redirect the filament to the right or left of the printer
- slot the L shaped arm in the place where the pulley can freely redirect the filament where you want it. There are 8 possible positions for the L-arm
- the L-arm is press-slotted in the main arm, and a single M3 screw holds it all together.
