you need the attached file. Keep it in the same folder where trial.scad is
placed

For some reason, the trial,scad only gave me the outer.

Any ideas?

here is the pure openscad version

you need to keep both these files in the same folder

If the idea is to 3d print, then most slicers  orca/cura, etc. let you
print infill patterns with various line widths, and orca for example can
create basic shapes and boolean transforms. I think for a simple grill,
it would give interesting mesh patterns with little effort.

Create a simple frame in openscad if you want , probably quicker to add
the fixing holes and other details in cad,

linear_extrude(8)
difference(){
square(100,true);
circle(d=90);
}

then in orca/whatever, make a cylinder a bit larger than the hole,
choose the infill for that part, thicken the infill and space as
required, and merge that into the frame. You can get very fine and
strong meshes, if needed.

Hi,

Yeah, I'd done the infill trick on a simpler design.

This particular one is part of a more complex part, which why I originally
went down the STL manipulation route.

Thanks,

Richard.
