ive had the same filament guide for years and quite liked it but it finally broke and couldn't find it again. when i found this design i liked it but it didn't any cable management like my last filament guide had so i just threw it into tinkercad and added one. after printing it out i noticed the hook was too small, so i enlarged that and went to install, well crude the guide was 7cm too low to line up with my extruder, back to tinkercad to split and add height, its rough but itll work.

use whatever wall count and infill you want its not a piece under any stress really
USE SUPPORTS for cable hook
