So I’ll include the blend for this one FanFilterShroud.blend (791.2 KB)
So… I’m new to this, and it’s possible/likely I’m doing something very wrong. But all I ‘tried’ to do, is make 5 cubes, one of them basically a square ‘ring’, and the 4 smaller ones in each corner. This is intended to be the right size/shape to screw a PC fan to. Very simple, very basic.
Tried to export the stl to my 3d printer, and the mesh is… broken beyond belief. Won’t slice even vaguely correctly.
Tried the fixes I could find in guides. Normals to the outside. Took a look with select-all-nonmanifold, and it seems to have a bunch of non-manifold parts. No idea why, and there doesn’t seem to be any way to fix them.
Tried a remesh, thinking this might solve the problem. Maybe it does, I haven’t gotten that far yet, because the only way to remesh and have a result that is still a square, is to go up to Octree 9, increasing my verts from 400 to 300,000. Which makes my pc chug. And when my PC is chugging when trying to render a cube, then I’m definitely doing something wrong.
So yeh… what did I do? And what shouldn’t I be doing?
In theory I guess if I knew more about it, I could go in and fix the non-manifolds manually… I think there’s only 16 or something. But this is literally the simplest object ever made. If I was on an actual big project with thousands of verts, and then have to manually repair them to get it to print… impossible. I must have done something massively wrong, I just can’t see what. The most complicated thing I did was a boolean-difference to make the screw holes.
