6into1 Filament Interchange (Filament Splitter)

Couldn't find any decent 6into1 splitters out there so made this.

PTFE tubing is held into place with 6mm collets - readily available from places like Amazon, etc.

• Pathways for filament have a 3.5mm bore, allowing for a non-cut tip when colour changing.

• The interchange works as a 3-2-1 - Initially fed via two rows of three inlets, converging into two feeding lines, finally merging to become the outlet pipe.

This has been tested successfully on a Voron 2.4 r2 (see images for a quick, 5 colour, test print).

Printed in ABS, all holes are modelled with shrinkage in mind, you should have no need to rescale if also printing in ABS - I cannot speak for other filament types.

Coming in at 80mm, and weighing around 15g when printed, this interchange is compact and robust, allowing for quick colour changes without the need to cut the tip.

I've been testing with it sat directly above my printhead, with a park position of 210mm on a Voron 2.4 r2, toolhead is a Stealthburner with Clockwork 2 extruder.

Print Settings:

• ABS

• No brim

• No raft

• 4 perimeters

• 0% Infill

• 0.4mm Nozzle

• 0.2mm Layer Height

• No supports

• Print upright (model comes in correct orientation)

Print time for me was around 45 minutes.

There is no bypass as this is going on toolhead 0 of the toolchanger I'm building - I will have other printheads for flexi-filaments.

At this point in time, I have no intention of uploading an .stp

9into1 coming very soon...
