probably quicker than finding just what you want. Print in ABS & acetone smooth.

Thanks, that's actually rather nice-looking. (for what it is.)
Plan-B might just be to get some graphic overlays from JRPANEL.COM and just cut a standard box to fit.

That being said, how many "hobbyists" actually stick things in
(purchased) enclosures? Everything I happen to see on YT is a 3d
printed thing. That might explain why you're having trouble finding
what you want as a product that's already available.

rectangular shape, it has an opening for a 1602 display
and below that three moulded buttons. there are keyholes
in the back for wall-mount. It looks like possilby intended
for an electronic thermostat.
Very cheap but fails most of your other requirements.

IP42 seems ambitious on a device with a battery compartment and an
RJ45, passing IP42 with a 1602 display would mean a window in front of
the display or some sort of verandah.

Pactec has some nice enclosures. Bezels are hard to find, unlike 20-30 years ago when LED displays were common. They can be 3D printed, for small quantities. Here is an example with a 9V battery compartment:
https://www.pactecenclosures.com/product-detail.php?productid=163&seriesid=62&classid=27
I have a couple of their TR series.
I also have a couple of these:
https://www.ebay.com/itm/293461593539
86-Plastic-project-box-enclosure-case-for-diy-LCD1602-meter-tester-with-buttN-sc
No battery compartment, but they have a hole in the back to run wires into them. It shouldn't be too hard to use the two slotted mounting holes to retain a battery cover, and they are cheap, at around $2.50 each.

Unprotected 18650 batteries do not have an electronic circuit in the cell packaging. Because of this, there is always a danger of over heating, short circuiting, or over discharging. Unprotected batteries are also much lower in price.

He said ten a month, not ten each. These days $10 each sounds like
it would be sure to be super cheaply built as well.
A solid, hobbed out box and seal. Keep the electronics and the
battery safe and dry. Yeah... that's the ticket.
And I think china made 25 for us pretty quick turn and pretty
cheap. I cannot remember the price. email on a different box. It
was 5 years ago.

At that qty 3d print the box to what ever specs and shape
you need. Hammond boxes will probably run you north of
$10 each.
