Is there a Knurling featurescript available? (like Thread Creator)

Hello All,
I am looking for a featurescript which creates knurling on my parts. I am looking for something that takes a cylindrical face and cuts the pattern into the solid body. Normally, I would use cosmetic knurl, but this will be 3D printed so I need geometry to be modified.
I am specifically looking to make a checkered knurl pattern per ISO 13444:2012. If a featurescript is not available then I will gladly accept modeling tips on how to model this correctly.
I already know of the cosmetic knurl featurescript which works great and helps performance in models where knurling impacts performance.

Yes, the cosmetic knurl featurescript is from me. But I don't have a script to actual 3D modell it.
@michael_mcclain
If you want to 3D modell you have to sweep the profile along a helix and create a new body. Create a cylindrical pattern and substract it from the main body.0 -
@sebastian_glanzner You can see my method of creating the knurling here:
https://cad.onshape.com/documents/3ecbecb8e65b8ee9f600c960/v/e73a398fae7a2a34f7014dab/e/28e56f0c3fc37d134a971846
I decided to use a projected curve vs a helix to control the angle of the knurl as specified in the ISO standard. How can I get the pattern qty correct to get sharp points on the knurl face?
I welcome any advice or tips on how to model this better.
Thanks, Michael0 -
@michael_mcclain Thanks for the link!I made a copy and could get rid of some sharp egdes:
The top face is now smaller (0.25mm wide). I also used a helix and calculated the correct pitch for an 60 deg angle. I shared the document with you. The regeneration time is quite high!

I had another idea to reduce the regeneration time!
I created a small pyramid and made a few patterns. It is not an exact solution, but the regeneration time is reduced from 56sec to 2.5sec

Looks like this document no longer exists or isn't public. Did you happen to stash the FeatureScript somewhere? Would love to take a look!michael_mcclain said:@sebastian_glanzner You can see my method of creating the knurling here:

I didn't make a featurescript for a geometric knurl and instead just made an example document showing the features I used to get a knurled pattern. I made the document public and updated it a little to explain the features.
Just be aware that knurling makes studio regen times very slow. That small part has a regen time of almost 20sec! I would recommend using this cosmetic knurl featurescript1
