Square-Yo V2

I'd previously made a 3d printed square yo-yo as a joke freshman year but I decided it was time to take it seriously. I learned one key feature in the last iteration; where the squareness is matters a lot. So although the outside of the body is very square, the inside is circular, resulting in a very high performance silly yoyo.

First step preparing the stock!

2 nice and shiny blanks.

As usual this required at least two setups but I decided to use the squareness to my advantage because I was milling the yoyo. First I made the cups:

Followed by the body:

One issue with making a square yo-yo is that the clocking of the halves matters. Typically the aluminum body of yoyos is tapped and a set screw threads into both halves as an axle, but I just drilled through holes, and used nuts to allow for the right clocking.

This was definitely the best yo-yo I've made at MITERS, primarily because it's so much easier to make square things on a mill! haha
