I bought an OXO vegetable spiralizer a while back to make zucchini spaghetti. It is awesome sauteed with a little garlic and olive oil! Turning the zucchini by hand takes forever and makes my wrist hurt. Enter the power take off from my kitchenaid mixer. I had to go through an iteration or two to get this right, but the taper and square shaft segment are pretty good now. It is a very specific print, but if you have one of these spiralizers, then this is such a life saver.
A video of me using it is included below. Cutting a big squash like this in half makes it a lot easier.
