Yoyo CAD & Prototyping Adventures

Love this one. Maybe its from all the cuts on the profile, but the cup underneath the rim to the hub looks super nice as well. Would love to see a shot of the profile shape.

Thank you so much for the lovely comments. I think I like this one more than the first one. Still very rough on the sketch but I’ll upload a cross section soon.

We did something similar with the 3145.

Inspired by the beautiful Cut (hspin).

I like this one better too tbh.

Do you remember the prototype sold at worlds 2008? I wanna say it was called the LCY and had a bunch of cuts but can’t find the info on it anymore.

Edit:
Found an old post about it but no pics. I remember how cool it was at worlds but was so expensive.

Yep, I do.
It had a lot more cuts than the final Cut.

Here’s the cross section. Still need alot of work!

Keep in mind too that if you’re designing around a D bearing you can get away with a pretty low weight. 61g sounds light, but it will feel significantly heavier with a D bearing than a 61g C bearing yoyo.

Just for example - The Sturm Panzer Leo Sniper Mk2 7068 weighs in at 59.4g and still has a good presence on the string. It’s bi-metal so a little different, but you can definitely get away with sub 60g on a D bearing design without it feeling too light.

This I like. Wish there were more bimetal organics. I personally like a bigger diameter with a moderate width so the specs are looking pretty sexy .

That’s very useful information I was only wondering if I should bump up the weight a little but think I’ll stick to the 60-61 range.

Oh, MarkD, I was just wondering whether you could make a tutorial for noobs like me on how to prototype an easy beginner yoyo using Fusion. Nothing fancy, just a basic in-depth explanation of the different tools, and how to start making a yoyo in Fusion. I respect if you don’t have time or don’t want to, but it might be something that could help a bunch of people.
(If you are interested, but don’t want to share your voice, you could maybe use a voice changer?)
Thanks!

This isn’t a tutorial (didn’t have time to make that today) and there’s no audio, but it’s the entire process from beginning to end, with mouse clicks highlighted so you can see where I’m clicking.

Super cool @MarkD! I’m sure this will help many!

I cant do bimetals, help idk how to make one

Gotta design the ring in another sketch.

Or in the same sketch. You can revolve multiple different bodies out of the same sketch as long as it forms multiple bodies.

Final design all refined.


Diameter 57.4
Width 49
Weight 60.4g
Ds bearing

All ready for next step😬

Thank you all for your advice and have a lovely Christmas everyone.

Epic!

Been learning FreeCAD, which is actually free (and open source) rather than the restricted personal/demonstration versions of the larger CAD packages.

Also, POV-RAY for rendering. It’s not nearly as easy to use as Fusion’s built-in raytracer, but I’ll get better at it with time.

Still can’t find a weight or MOI calculator in it?
