OpenSCAD code - is a description of your model in terms of a few

difference() {

STL file is a list of triangles which make the same outer shell as your
model. OpenSCAD makes this complicated transform from shapes to triangles.

outer loop
vertex 1.76777 1.76777 0
vertex 2.5 0 3
vertex 2.5 0 0
endloop
endfacet
: (and so on for 300 lines) There is a binary/compressed version, but
the description is still just triangles.

Gcode is what a 3D printer understands - it is the exact list of moves
that the head has to do with how much plastic to squeeze to trace the
outline of your shape, layer, by layer. It will optionally create moves for
filling the inside or support for overhangs. Such a program is called a
SLICER and the printer will come with one.
G92 E0 ; reset extrusion distance
G1 Z2.330 F6600.000 ; lift Z
G1 X-0.000 Y1.505 F6600.000 ; move to first perimeter point
G1 Z0.330 F6600.000 ; restore layer Z
G1 E3.00000 F2400.00000 ; unretract extruder 0
G1 F1500
G1 X-1.064 Y1.064 E3.09259 ; perimeter
G1 X-1.505 Y0.000 E3.18517 ; perimeter
: (many similar lines)
G1 X1.515 Y1.515 E4.65860 ; perimeter
G1 X0.055 Y2.120 E4.78559 ; perimeter
G1 X-0.000 Y2.143 F6600.000 ; move inwards before travel
G1 X0.384 Y0.843 F6600.000 ; move to first infill point
G1 F1500
G1 X0.843 Y0.384 E4.84815 ; infill
G1 X1.097 Y-0.229 E4.91215 ; infill
:
(and so on for thousands of lines)

The 3MF still basically deals in triangles, and attributes (surface,
infill material, picture, ticket info ... ) which probably are not used by
your slicer/printer.

Subject: [OpenSCAD] Export to .STL / .3MF for later 3D-printing.
Hi!

Thought to create some objects in openSCAD, to print later.
I do not have my own 3D printer (yet).

One I talked to, wanted to get the drawings in .STL or .3MF. (I don't know
the difference).

If I had my own printer, have I been able to print directly from openSCAD?
(Without some export?)

In the openSCAD, no errors or problems occur.
but
The drawings I tested to export from openSCAD have given one or another
error message.
One message .:
WARNING: Object may not be a valid 2-manifold and may need repair!

Another message .:
WARNING: No top level geometry to render

What to do?

Jan Öhman wrote it failed in Render/F6, but works in Preview/F5 - in so many words. I tried and got the following

First model

F6 Error: WARNING: Ignoring 2D child object for 3D operation in file , line 53

ERROR: CGAL error in CGALUtils::applyUnion3D: CGAL ERROR: assertion violation! Expr: G.mark(v1,0)==G.mark(v2,0)&& G.mark(v1,1)==G.mark(v2,1) File: /mxe/usr/x86_64-w64-mingw32.static.posix/include/CGAL/Nef_S2/SM_overlayer.h Line: 303

Which I think is pretty selfexplantory: Passed a 2D shape to something that expected a 3D shape - but you have to read the whole code to find it ... which I think Jan is more qualified to do :-)

2nd part

... which is one of those where zooming or rotating the model in preview takes >5 second

And I didn't bother waiting for the F6 error ... ;-)

Of course, we do not know if the above shapes I got are the ones that Jan wants - there are also sections of code commented out.

(From the comments it seems these are to be nice and alternative covers for wall outlet/switches.)

STL file is a list of triangles which make the same outer shell as your model. OpenSCAD makes this complicated transform from shapes to triangles.
solid OpenSCAD_Model
facet normal 0.92388 0.382682 0
outer loop
vertex 2.5 0 3
vertex 1.76777 1.76777 0
vertex 1.76777 1.76777 3
endloop
endfacet

: (and so on for 300 lines) There is a binary/compressed version, but the description is still just triangles.

Gcode is what a 3D printer understands - it is the exact list of moves that the head has to do with how much plastic to squeeze to trace the outline of your shape, layer, by layer. It will optionally create moves for filling the inside or support for overhangs. Such a program is called a SLICER and the printer will come with one.
G92 E0 ; reset extrusion distance
G1 Z2.330 F6600.000 ; lift Z
G1 X-0.000 Y1.505 F6600.000 ; move to first perimeter point
G1 Z0.330 F6600.000 ; restore layer Z
G1 E3.00000 F2400.00000 ; unretract extruder 0
G1 F1500
G1 X-1.064 Y1.064 E3.09259 ; perimeter
G1 X-1.505 Y0.000 E3.18517 ; perimeter
: (many similar lines)
G1 X1.515 Y1.515 E4.65860 ; perimeter
G1 X0.055 Y2.120 E4.78559 ; perimeter
G1 X-0.000 Y2.143 F6600.000 ; move inwards before travel
G1 X0.384 Y0.843 F6600.000 ; move to first infill point
G1 F1500
G1 X0.843 Y0.384 E4.84815 ; infill
G1 X1.097 Y-0.229 E4.91215 ; infill
:
(and so on for thousands of lines)

The 3MF still basically deals in triangles, and attributes (surface, infill material, picture, ticket info ... ) which probably are not used by your slicer/printer.

Subject: [OpenSCAD] Export to .STL / .3MF for later 3D-printing.
Hi!

Thought to create some objects in openSCAD, to print later.
I do not have my own 3D printer (yet).

One I talked to, wanted to get the drawings in .STL or .3MF. (I don't know the difference).

If I had my own printer, have I been able to print directly from openSCAD?
(Without some export?)

In the openSCAD, no errors or problems occur.
but
The drawings I tested to export from openSCAD have given one or another error message.
One message .:
WARNING: Object may not be a valid 2-manifold and may need repair!

Another message .:
WARNING: No top level geometry to render

What to do?
