Spring loaded cutter nozzle for my churro maker

When using my churro machine I found it awkward to take my hand off the crank and reach for a knife to cut the dough. 

With this nozzle you turn the ring a less about 1/6 of a turn and it cuts the churro. It's spring loaded so the blades return to the open position automatically.

I don't think it really needs instructions but if you have problems assembling it message me and I'll put together an assembly sheet.

To save time I used a much simple diaphragm stl that I found online and used it to work out the blades geometries.
