Summary

Prometheus 3 in 1 Filament Switcher for E3D V6 Mount I created to replace A10M mixing hotend.

Uses three PC4-M10 Fittings and screws into top of E3D V6 Hotend.
Insert 35mm length of 4mm bowden teflon tube to fit inside where it mounts onto hotend.

Use the finest layer height that your printer supports. Use 4 walls.
200C print temp gave smoothest result at 30mm/s print speed.

This is for switching filament. Printing one filament at a time. NOT FOR MIXING.

V7 has a higher res male thread and made them longer so you can lock in place with a M10 nut, as requested in comment. (I have not tested this.)
