Umbilical Clip w/ PTFE Guide and Filament Support Voron Logo

Umbilical Clip with provisions for bowden tubes and cable support provided by 1.75mm filament. 

For 7.2 - 7.5mm Umbilical Cables. Can be modified(step file included) to fit other umbilical diameters.

I am currently using the LDO Nitehawk tool head board for my V2.4 and the umbilical that came with the kit is really flexible. I first used a clip that coupled the bowden tube and umbilical together, which helped with the floppy cable but overall I was not happy with how it turned out. I then decided to design a clip with a bowden tube and filament guide to give the cable some more support. It is a definite improvement, plus it also provides an opportunity to add a little contrasting color to your umbilical setup!

I recommend using some sort of filled filament(CF or GF) in ABS, ASA, Nylon or PC for the umbilical support if you are running an enclosed printer. I have been using GF ASA and it has the correct amount of stiffness and flexibility without being too brittle. I have been happy with the design, so I decided to share it with you guys!

Assembly:

I found it easiest to stack all the clips you are planning to use right on top of each other on the umbilical cable, then feeding the filament through. To secure the ends of the filament, I simply loosened the umbilical gland, slid some of the filament down and tightened the gland back up. I am currently using the PUG(parametric umbilical gland) and am really happy with it. If you are using any other umbilical solutions(PG7 etc.) you can simply ziptie the the ends of the filament.

Printing:

ABS or ASA recommended

Voron Settings, but the part is so small it doesn't really matter.

You should calibrate your printer before printing, the filament guide hole is meant to be snug, but allow for filament diameter variance.

I have included the .step file as well if any adjustments are needed or if anyone wants to further the design with a remix
