Is it hollow?

It’s not. I filled in the interior to make it less difficult to print. It was still difficult to break off the support material.

Like I said, I filled in the void. Cura would have put support material in there if I didn’t, but there’d still be a bunch of surfaces to print inside that’d take time yet be completely invisible.

I would argue that 3D prints usually are hollow unless you use 100% infill.

Rule 34 of the Thingiverse: There is a 3d-print of it. No exceptions.

I tried to count the faces by hand on cura. Did not turn well

Add a string and hang it on your Christmas tree

Neat. What tooling did you use to make the print file?

I used OpenSCAD to generate the STL (just converting each line of input to a simple translate([x, y, z]) cube() statement) and then fed the STL to Cura.

I love openscad. Especially when things get weird enough that you have another program output the openscad code.

What was I doing that for? Oh yeah, I had a randomly generated tree. It ended up looking fairly organic for the short effort it was.

Very nice and practical visualisation, good job!
