think&have multicolor blending hotend

Multicolor hotend for
2-4 filaments with 1.75mm ,
standard M6 Nozzle,
only for bowden extruders,
standard 50 mm fixation,
fan recommended,
small milling machine or lathe needed for machined aluminium parts.

The parts are described in OpenScad, but they can not useful be printed. You dont want a heating block made of ABS.

If you want to turn your single Filament 3D-Printer into a mutlicolor machine, this hotend might be the right choice.

Multicolorprinting whith a single nozzle is a bit different to two hotend printing, there are some disadvantages and advantages.
