Worked so well I immediately printed a backup in case the first one breaks. Not going back to stock.

It will probably be easier to use if you turn it the other way. The side you have on the back is intended to be left open for gear cleaning, and the pinch to release is probably more accessible if it's in the front.
Yes, for gear cleaning it's easier if it's the other way around but because the hot end is off-centered (to the left of the photo) it would be harder to change the filament. I had to choose wether I disassembled when cleaning or changing filament. I will in the future change the whole assembly in that in mind.
