Prusa i3 MK2 / MK3 - Filament Guide

Simple filament guide for MK2/S + MK3/S printers.

Main design considerations

V2 (Green)

• provide enough gap for filament movement as Z rises
• higher arm in respect of spool to aid filament path / extruder
• reduced thickness of arm

V1 (Blue)

• ensure filament not overly constrained during max Z height
• avoid x-carriage catching on guide to reach max Z
