Lack filament port

Was getting annoyed at the scratching of filament as it passed through the ports i was using.

This is a semi bowden solution using 4mmOD bowden tubing and M10 bowden fittings (the ones I have the tube passes straight through.

Enclosure hole needs to be 10mm. They are held in place by the tension between the couplers and you may need to sharpen one end (in a pencil sharpener) so you can feed it through the coupler the wrong way.
