Yoyo CAD & Prototyping Adventures

I’m thinking of protoing a full size wide boi out of steel, looks like this:

The walls are mostly like, .7mm.
I don’t really know how thin I can go, but .7 seems ok.
At least at the prototyping stage it will become clear :smiley:

That looks epic

3D CNC Titanium printing. Ive seen this done in cycling. Probably do a Yo-Yo, technology these days

Metal 3D printing has always interested me. It might not be the end all, but making a blank and just machining the surface might be the go to with them.

That surely looks really precise, gotta look at the prices on that tech.

im really new to the yoyoing scene (1 month new) and would like to learn to model and make yoyo, but where do i start

This thread should get you started.

So I’ve done some modeling for a yoyo and I’ve finished! Here are some picture

Oh man! This is pretty awesome! I would absolutely love to pick on up whenever you decide to put them on sale. I’d give a crack at installing a modern bearing seat into it and maybe give the yoyo a powder coated finish. The bearing seat design you implemented potentially could have been revolutionary for the time. I don’t think the modern bearing seat design came out until the mid 2000s, @yyfben2.deactivated would know the answer to this.

Oddly the first bearing yoyo had a similar bearing setup with oversized inner race.

CAD/Visualization tooling updates!

I found an interesting Blender plugin called Sverchok nodes, which allows direct interaction with FreeCAD files from within a node tree view in Blender.

Sverchok: Welcome to Sverchok’s documentation! — Sverchok 1, 2, 0 documentation
Blender: https://www.blender.org/
FreeCAD: https://www.freecad.org/

The setup for it is a bit wacky at the moment (requires a specific version of Blender, 3.2.0, and running some command line stuff on your computer to pull the correct FreeCAD binaries/library files into a directory for Sverchok to use) but the results are making my workflow simpler.

Previously, I had to export DXF (2d) drawing files from FreeCAD, import them into Blender, then add a Screw modifier to “revolve” it into a solid. This workflow was repeated for ANY change.

Now, after linking together the node tree, if I change something in FreeCAD, I only need to press the UPDATE button on the ReadFCStd node and it brings in the changes.


Example node tree with 4 objects (Shell, Cap, Bearing, Hub), the steps used are:

  • File Path → For selecting the specific FreeCAD file
  • Read FCStd → Reads a part out of the FreeCAD file (one per part, in my case)
  • Solid to Mesh → Converts the “Solid” output of the previous node into a triangle mesh, I am currently using the Standard mode and adjusted the parameters to make the result pretty high fidelity.
  • Mesh Viewer → Outputs the Mesh into Blender’s scene, where I can apply regular Blender features like materials
  • Matrix In → I am using this to scale all the parts to 1% of the original size, since there’s a scale mismatch between the default units in blender and FreeCAD.

The initial setup is a bit of a pain but it’s worth it, I think!

Here’s one of my private projects for my dream yoyo that will probably not be produced, the M-ACRO-SS.

Took some key designs from my old throws back in 2015 plus the latest yyr models.

(rebellion acro for profile, dome cup from yyr ae models)

Its a bi-metal construction that has a titanium rims and 7068AL

Specs are:
Diameter: 55mm
Width: 48mm
Gap: 4.9mm
Weight: 64grams

i’m currently designing a yoyo in fusion 360, does anyone have the yoyofactory axle specs and thread designations?

As a starting point for 6061 aluminum, use a 10mm or 12mm long m4 axle.

edit: Coarse thread

what’s the thread designations and diameter tho so i know what taps to use
