I’ve been building 3D parts by layering and binding together with chicago screws, like the previous post but for layers.
You could use this for a variety of precious objects. I’ve shown a pyramid outline, but you could do any shape you wanted, including straight walls. You might want to sand/polish straight walls for a better look.
I used my own M4 screws to compensate for the post length and the overall Z of the layers.
The vial holds a sample of nanoparticle black paint. Super black.
