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.

https://www.aliexpress.com/item/32949006436.html 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. -- Jasen.

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. -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEBcqaUD8uEzVNxUrujhHd8xJ5ooEFAl5ndhQACgkQjhHd8xJ5 ooGWWQf/Qbxno3cMtMAPr2ZMn+VPj/Av35qZp1bJj2is0AFWR/D6Ba03Ceks8oqL UyD1huqDy8NVKD7Y1O8mgsV6yQKCj2PRTmXUw4bDHcdwHvlK3DnL+RmHOQng7SuB 5vGDRtULElk9gpqxVCLcvcWkRJTAZKAh7Z1iZN3KDF9krZIuyjPqzFqlX9Psinu/ FGtLxRsOTMdk+L2zrp4T83HkqB8wnnlSABcL9X2c98qxTe4oc5C4LDqEacQQhYml Fsxvaqk5ZRJNHgKHv5NfPzaZw1xuI9VcJaeHqCAum4uXyZkIssQpXmzYXa5za58j sIzAyj8ce7PhL4XxXyoBdJUIhhW9sw== =ggx0 -----END PGP SIGNATURE----- -- |_|O|_| |_|_|O| Github: https://github.com/dpurgert |O|O|O| PGP: 05CA 9A50 3F2E 1335 4DC5 4AEE 8E11 DDF3 1279 A281

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.

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