Revolve it on the same plane as your sketch

Looks nice! What grade aluminum are you thinking of using? A couple walls look thin.

Do you mean 7068? Minimum thickness for that should be >0.8mm but only if you’re doing something extreme, and it’s mostly not necessary to get that thin. I’d recommend at least 1mm.
Given that, you can carve your cup much, much deeper. It only needs to be like 1.2mm away from the bottom of the bearing/pad moats. That other weight there isn’t doing much for how the yoyo plays except make it heavier in the middle.
What’s your current weight per half?

Forgot i didn’t post this here. Updated that second design a couple days ago. Top is the original half so you can see the changes a bit better.

Wow, it sure shrunk a lot!
It looks like the string might catch on the response bump, and maybe even on that cut near the rim.
You should also be able to blend the rim better into the face of the yoyo so that there isn’t that sharp-ish bit.
What I like to do for rims is extend the fillet arc all the way around and draw a tangent off of it to make the wing part of the rim.

revolve it, set the material to your desired aluminum, and view the properties of the body

thx
17 grams for each side, I don’t think that’s right ill double check
Which material do you have it set to? 7068 is around 2.85 g/mm^3
The weight sounds right for the drawing you sent earlier. You definitely need to beef up the dimensions!

right now im making one thats 6061 and the only reason is I cant find 7068 and I don’t want 7075

Make a duplicate of 7075 and adjust the density a bit in the material properties. It’s already really close to 7068. Fusion doesn’t come with 7068 since it’s not a common alloy.

Why don’t you like 7075?
