3D model description

For other Prusa MMU stuff: https://www.thingiverse.com/AbeFM/collections/abes-mmu2-stuff

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 is a work in progress, it needs a better lock to hold the tube, it works for MMU printing but could be better. Be careful not to overtighten - check the filament still runs freely!

I've added a slightly beefier version in case anyone has broken theirs, called "heavy duty V16".

I also intend to add a guide/funnel at the end to make it easier to blindly shove filament in.

I designed these for use in my over/under counter MMU set up, including these minimalist spool holder stands: https://www.thingiverse.com/thing:3474307

Another user has found you can scale the entire thing 1.5x to use for 6mm bowden tubes.
