Weld seams between gyroid meshes

Thanks for the response @DanielPiker. I was hoping to define the x, y and z dimension in the gyroid.gh definition I sent for a regular Cube without trimming. I noticed the dimensions I get for the entire model is different from what in put in at x, y and z. Is there a way to create say, a 10mm x10mm x10mm box of gyroid?

Can you create a BoundingBox of your final Gyroid cube, DeconstructBox to get the X,Y and Z dimensions and then Scale NU to get it to the size you want?

Your definition probably sets the X, Y and Z for the initial mesh and the final size is dictated by everything that happens after that.

@martynjhogg can you help me out here? I’m finding it difficult to make it work

I can’t open your Gyroid.gh file because I don’t have Millipede but the attached file takes a mesh and scales it to be 10.0 in X, Y and Z directions.

SCALE_NU.gh (10.8 KB)

Many thanks to Daniel Piker

Needless to say I could not have done this myself - what I did was take Daniel’s GH file and tweak it a bit to make the object 3D printable. My first attempt to print failed because no side of the geometry is truly flat, which means there were only tiny points of contact with the printer’s print bed. These points were not large enough to hold the part in place. So I whacked off a small amount of the bottom of the geometry and made it flat. This allowed the print to complete in 7 hrs. 52 min.

Daniel was generous enough to post an alternate design, so I combined that with the first one and added some GH components to do the bottom fixing. I’ll be happy to post the whole GH file for anyone who’s interested, but it requires some explaining because it uses 3 separate solutions.

The STL file for printing is here: Thingiverse and Pinshape.


@martynjhogg THANKS A LOT!! I have been able to define the dimensions with your example. Thanks for the amazing support

Hi Daniel, Thank you very much for pointing me to this thread. Great results! I’m curious if you have any tips for cleaning up the mesh edges when you follow this minsurf_trim.gh method, as the cutting produces rough geometry when thickened. I’ve tried most of the weaverbird subdivisions and smoothing objects at various steps in the process without much luck.
