Yoyo CAD & Prototyping Adventures

Monometal, 60mm x 50mm, 61g
Sort of a big exia with hollow bones.

Recieved a photo from the manufacturers.
Now really excited to get my hands on it and throw it. Hopefully it will play as well as it looks!!!

Yeah that looks fancy. Very cool

Thanks. Now I’m just nervous about how it will perform.

It reminds me of an X3 stampede crossed with an UNPRLD Abduction

Here is a great article to read, by Harrison Lee of CLYW, about the design of his upcoming signature yoyo, the Otter.

Working on a video series. I’ll be re-designing a yoyo idea I’ve had in my head, working mostly from scratch, and showing (hopefully) the entire process from concept, CAD and product visualization, and eventually prototyping and production.

Part one. This one is all on paper.

The fact that you drew it out on paper is really cool

Part 2 is up!

Transferring the paper drawing to FreeCAD, starting with the “monometal” outline of this bimetal yoyo.

Super cool video Mark! Thanks for sharing!!!
Can you possibly show how you model the threads for the axle in Free CAD in your next tutorial?

How have you found Free CAD as compared to Fusion 360?

How did this print turn out? How did it play? I don’t recall seeing pics of the finished piece.

I don’t typically model them for yoyo designs, because from my standpoint all I need to do is pick a size of axle, but I can cover it in a short addendum video after I find a method that works well for me.

Fusion 360 is definitely the way more advanced tool. But FreeCAD is able todo the job for free. So up to you what u wanna use.
Tutorials on threads exist a ton e.g. (Be aware in 3D printing you will not be able to print yoyo threads (M4) in a good enough quality. Just make a 4mm hole and screw them in)

It played sh*t… Since the string gets caught on the small edges.

This one I play a lot. Very good player imo

It’s much more free, and the several weaknesses it had I’ve been able to shore up by writing a couple macros for it, and using Blender for product visualization instead of the CAD tools.
