90* Under Counter Bowden PTFE guide for Filament Spools

thingiverse

Simple guide to keep bends reasonable and route bowden tube under/to/past spool. And I've added a clamping one V14, which I may post as a separate item later. This setup is still in progress, requiring a better lock to securely hold the tube, although it works for MMU printing, room for improvement exists. Be mindful not to overtighten - check that the filament still moves freely! I've also created a slightly beefier version called "heavy duty V16" for those who may have broken their original. A guide/funnel will be added at the end to simplify the process of inserting filament blindly. These designs were specifically made for use in my over/under counter MMU setup, which includes these minimalist spool holder stands: https://www.thingiverse.com/thing:3474307 Another user has found that scaling up the entire design by 1.5x can be used successfully with 6mm bowden tubes.
