Thanks for all the help so far, much appreciated and will keep my busy
for some time.

Meanwhile, where am I going wrong with this first very simple (!) test
please. I just wanted to print a small rectangle containing two pieces
of text to:

1. Give me a feel for font size
2. Let me try filling some taped hollow text
3. See what 1 mm high embossed text looks & feels like, prior to
   trying that with white PLA..

But Cura shows that it will at best fail to print the latter, and I
can't spot why?

difference()
{

translate([0, 8, 0])
cube([30, 7, 3]);
translate([2, 10, -0.5])
color("navy")
linear_extrude(5)
text("Hollow #3 ", 3);
}

translate([22, 10, 1])
color("lime")
linear_extrude(3)
text("#4", 4);

 This is largely a '3D printing' post, but hope I'm not too far OT.

 I've not yet made a print including text with my Ender 3 V2. But
 I'll soon need
 to do so and would appreciate some advice on a few practical
 points from more
 experienced users please.

 The 10 text labels will be on the top surface of a rectangular box
 lid, which
 has dimensions of 175 x 95 x 3 mm. Maybe a bit thicker if
 necessary. The labels
 (like On/Off, Up, Down, etc) will be near holes made for various
 buttons and
 switches. Each label will therefore be fairly small. I want them
 to appear flush
 with the surface, white on my black PLA filament.

 One option might be to fill with something like 'Hard As Nails'
 glue/filler,
 wiping the surface clean before leaving the filler to set.

 But ideally I'd like to do it by stopping the printer just once,
 changing to
 white filament, and resuming (something else I've not yet tried).
 If I go that
 route, what changes do I have to make in OpenSCAD and/or Cura, so
 that the stop
 occurs at exactly the right place?

 Would another idea be to make each label say 1 or 2 mm high and
 push them into
 place? On reflection I suppose they could be printed as one object
 joined by a
 thin, easily removed line?

 All suggestions/tips/advice will be much appreciated.

In cura, turn on 'print thin walls - under 'walls' group. For fine
detail, reduce layer height and extrusion width in general.

PrusaSlicer is happy with it.

Found that and enabled it but still the same:

Any other settings you see there that might be the culprit?

Yes, we see your attachments. The problem is that the object is tiny. Can
you scale it up in x and y by a factor of 2 or 3?

Thanks for testing. That motivated me to install PrusaSlicer and load the
STL.
Attached or here:
https://www.dropbox.com/s/7v84l70rbextg5p/Hollow3and4.stl?raw=1

But when slices and previewed I still don't see the text '#4' on the right
hand
side. It looks almost the same as in Cura. And same after trying the
'Repair'
option. Screenshot attached, or here:
https://www.dropbox.com/s/xoywpxf9o7g3xpt/Prusa-2.jpg?raw=1

So, you do see all the text? Is it possible to export PrusaSlicer
settings? If
so it would be very helpful if you could send me yours please.

I'm rarely able to see my own posts. Could I get confirmation that my
attachments are OK please? Both the one attached and the link?
