I often find very nice designs, but not optimized, leading to a waste of filament.

But now, we have these tools:

  • use either Riham's online or my python standalone converter to turn your STL file to SCAD;
  • use OpenSCAD CSG tools to slim the design.

Keep in mind that things should remain strong enough and printable, at least as much as the original were!

On the screeshot, you can see how I removed a large inner part of the boosters¹. Also note that I used cones, in order to keep parts easily printable. I also removed a quarter of the part, just to show the process.

So does this help bypass how stingy OpenSCAD is with STL importing? I've often had problems using the import statement to get STLs so I can work with them, and even when they do work, they quickly start giving me CSG errors.

fma - in reply to thantik

Yes! I always had issues using CSG operations on imported STL. In most cases, it does not work at all. Here, it seems to work better (even if I can only see the result when I compile+render, not when I compile only)...
