Yoyo CAD & Prototyping Adventures

[JWaugh (Jacob Waugh)]

The second two are amazing

[MarkD (Mk1 Yoyos)]

Thanks! You mean the quad metal and the green one, right?

[tommywoh (@LSThrows)]

I shudder at the thought of trying to machine that quad metal

[MarkD (Mk1 Yoyos)]

Luckily it only exists in my “yoyo graveyard” design folder.

[JWaugh (Jacob Waugh)]

Lol no the quad metal was unsettling to look at, the last two I meant

[PCaliyoyos (Peyton Cali)]

these look really awesome.

[TurdFerguson69 (Levi Neal)]

Spent the last week or so figuring out 360. Here is what i have made so far. 51x42 weighs 59.8. A little smaller than i want and lighter. more work to do.

Oh shoot I should post these here too. I designed some tessellating yoyos, called tesellate so I could potentially make a bimetal version and add the other “s” I also made a dome display thingy lol

[MarkD (Mk1 Yoyos)]

An O shaped mid ring yoyo. Specs are still wacky but the shape looks nice.

[hobbygod (Dressel Designs)]

I like it!

[Glenacius_K (Spinworthy Glen)]

The profile and steel rims look nice, but the cup is too AR-T like for me.

[MarkD (Mk1 Yoyos)]

You think so? They’re not really know for their flat cups. Almost all of them have a concave hub.

[MarkD (Mk1 Yoyos)]

Here’s a “very mk1” version of the above. Really hard to manage center weight with this cup on an O-shaped yoyo, but that’s what undercuts are for.

[Legit_yoyostrings (Landis Johnston)]

holy dude that looks so good, it reminds me of a sf

[hobbygod (Dressel Designs)]

You have such great designs

[yoyojoe]

Awesome work

[Legit_yoyostrings (Landis Johnston)]

no joke this is the next thing I want from Mk1 its so clean looking

[Legit_yoyostrings (Landis Johnston)]

so my friend from my yoyo club @T4t3z0r88 said that you need to figure out somthing about the moment inertia when making Yoyos on CAD but what is that somthing?

@MarkD

[MarkD (Mk1 Yoyos)]

You can read about what moment of inertia is here: Moment of inertia - Wikipedia

Most CAD packages include a way to set a material on a 3D body and estimate the mass and moment of inertia.

Having a high moment of inertia is one thing that can make a yoyo feel “powerful”, because it requires more torque to get the same rotational acceleration. It’s analogous to rim weight.

When designing a yoyo, it can be important to keep it in mind, just as you’d keep in mind the dimensions and overall mass.

thanks so much, I’m going to start designing a yoyo this weekend just for the fun of it and to learn the beginning stages of making a throw
