Tidy Filament Guide For Ender3 V2 (Plus lead screw shield)

thingiverse

A very lightly edited version of hellwisp's excellent Filament Guide - https://www.thingiverse.com/thing:4810218 I used Fusion360 to remove a sharp edge from the original design's base plate that intrudes on the inside of the cone near the bottom, leaving a smoothly rounded surface all the way around the guide cone. This should help to prevent friction when filament is entering from below the level of the extruder or when working on higher z-values during prints. The guide itself helps to prevent high-angle filament entry into the extruder, which can cause scraping/rubbing of the filament against the sharp edge of the pre-drilled holes, particularly in the metal versions of the Creality Ender 3 extruder parts.
