I didn't send it to the "Empathy" site (whatever that is).

Dave,
I saw your post on the Empathy site. Not sure you realise that's rarely
by those on the Mailing List, so I'll copy its content in this post.
I'm no expert but FWIW I tried your file with the free repair tool at
https://www.formware.co/onlinestlrepair
and got a rather unhelpful message that won't please you:
"Sorry, this file was not fixable: Error reading your file."

Problem with "Difference" and F5 ...
Hi, I am running Openscad v2021.01 and am having problems with the
script.
$fn=32;
difference()
{
union(){
import("base_slide_heavy_
isn't subtracted :-
The "imported" .STL file is attached.
This is only a problem for the preview, the generated STL is fine.
What am I doing wrong ??
Regards,
Dave

the difference needs a translate down so you don't have colliding planes:
// Remove smaller diam, but higher, protruding at both ends
translate([0,0,-0.01])cylinder(h=h+.02, d1=d1-2t, d2=d2-2t, $fn);

Thanks both, appreciate the fast responses.
Sanjeev: Works fine and no errors!
Dave: No errors, but it did not give me the same result. Probably my
mistake.
Here's my revised code which I thought used your corrections?
// Creates a hollow partial cone
// Height = h
// Bottom diam = d1
// Top diam = d2
// center = true/false or 1/0; almost always use true
// $fn = typically 24 for control knob
// Thickness = t (same throughout)
module hollowCyl_Full(h, d1, d2, center, $fn, t) {
difference() {
// Larger diam, from which a difference is needed
cylinder(h=h, d1=d1, d2=d2, $fn);
// Remove smaller diam, but higher, protruding at both ends
cylinder(h=h+.01, d1=d1-2t, d2=d2-2t, $fn);
}
}
// EXAMPLE
hollowCyl_Full(9, 36, 28, true, 24, 1);
