This might be the right thread to ask for help with a 3d problem I've been working on for a year or so.

I have a resin 3D printer, and I want to make handles for it. Specifically, ultra lightweight handles using an irregular lattice.

OpenSCAD chokes on trying to union 100s of cylinders. Real tools cost $1,000s. Right now it looks like I'll have to write something to do the union in voxel space

It's not really because Show HN is specifically for people showcasing their work and getting feedback. But there are lots of other kinds of threads where it might fit up to an including posting an Ask HN of your own.

For work or hobby? Fusion360 doesn't cost a penny for the latter. (I'd love to use code or FreeCAD or ideally FreeCAD stored as sane human readable code, but none of the options are quite what I imagine.)

1. FreeCAD. I am not 100% sure what you are trying to do, but FreeCAD most probably con do it. And the forum is there to help you if needed.

2. 3DExperience Solidworks for Makers. It's something like $100/year.
