I've changed some minor things: 

• Made a little more space with the stepper, for E3D Hobb-goblin drive-gears.
• Printed tiny gears to glue onto motor-shaft, and idler-shaft. 
• Changed idler, so two MR105 bearings to fit. 
• Printed a 5mm shaft to the idler (You can just cut some steel or what-not), I like the flex the shaft gives me
• Modified hole-size, for M4 to mount it in the printer. Mine is a RepRap-XY, with sdavi's mods. 
• Changed to 12mm inductive probe

The gears can be printed with 0.4mm nozzle, however, I printed a bunch with 0.25mm, with a much nicer result. Slic3r takes some persuasion to print in 0.4, but it's possible. But had to go to Cura to slice 0.25mm, otherwise it wouldn't print. 

The idler bearings are glued in place. Make sure to turn the shaft a couple of round before glueing, so the bearings can wobble into alignment. 

All the parts is printed in PETG, works nicely. 

I have printed a couple of kilos of filament now, no problem what so ever. Before I would strip PLA in the V6, but the only thing stopping it, is maximum motor current.
