Had to fit HDMI & Displayport cables through 25mm/1 inch electrical conduit (building static limits it to 25mm). The issue is that the connector won’t fit through the commercial 90-degree corners.
Solution? Enlarge the profile while keeping the bending radius:
Some CAD and a 3D print later I have the solution no money can buy. That’s the power of 3D-printing and modeling.
Going to wager those are significantly more flammable that the original material. Probably alright for purely low voltage applications. But not something to take lightly. 3D printing thermoplastics are not safe as electrical covers, conduit, or boxes.

Whew, I for one, am glad a little dripping is allowed.
It’s not weird. It’s not gross. It’s normal and it’s allowed.
Almost any type of plastic that can be manufactured (and even some that otherwise sort of cannot) can also be 3d printed and almost all are available as filaments. Some of these filaments are very difficult to print, or very expensive, or very hard to find, or all of the above, but if you need 3d printer filament that meets any particular certification or material needs, there’s probably a filament for that, and it likely has official certification too. 3d printing is being used everywhere now, commercially and industrially. It’s not just for home-gamers anymore.
And even if you don’t find something you can print that will quite meet the same technical level of certification, there are still plenty of easy to print filaments that have quite good properties for things like flammability. It’s good to keep things like that in mind though, especially if you’re the sort of person who just defaults to PLA or PETG for everything. (I’m guilty of this)
I know everyone’s needs are different (I’m in Third World Nowhere, where building codes don’t exist and our solutions are limited by unusual practical circumstances), but isn’t HDMI-over-Ethernet a thing? I don’t know if I’d trust a 3D printed part with keeping water out in the long run
It’s a thing, but it’s either cheap and really sucks, or expensive and kind of sucks.
I am interested in it. Can you explain why it sucks?
The cheaper ones are generally pretty finicky, and often introduce weird compression. You’ll often find the stated achievable distances to require very good cabling with very good terminations.
If using cat cable was a necessity, I’d put the extra money down and get HDbaseT units. But I’d be pretty seriously looking into the various fully moulded active HDMI cables or even better, SDI solutions.

I’m no electrician, I don’t run a lot of cable, I’m just a maybe-slightly-more-competent-than-average DIY homeowner type
Personally though, I like having cables run through conduits when possible for the ease of running them. I’m not particularly worried about water or mice or anything, it’s just a lot easier to just drop a cable down a pipe or suck a string through them with a plastic bag and shop vac than to try to fish them through the walls, especially anything I might want to upgrade at some point down the line when a new standard comes out like Ethernet or HDMI.
Makes sense. I just meant standard conduit, Ethernet cable straight through the conduit. Not into the home network.
I’ve pulled connectors through odd gaps, I know how it is.

Again, I just mean literally running Ethernet cables into standard conduits, terminating them, and sticking a HDMI over Ethernet box on either side. In order not to modify the conduits. I don’t know what the bandwidth is for that kind of solution. I’m not presenting it as the only and best option.
Your solution is cool. My own conduits are surrounded on four sides by concrete, so pulling connectors through is something that I only have to do very very rarely. And more often than not I find myself having to change one thing to wireless or use something that can make use of multiplexing just so I can free up a bit of space in there to do something else.
My own network is still an absolutely atrocious 200kB/s DSL through decaying, water-damaged copper lines. And those aren’t going through conduits, those have had concrete poured right over them. Over the 2x1mm thick flat two-strand “cable” that was obsolete when the building was built decades ago. RJ11. Plastic sheath that disintegrates into asbestos or some shit when exposed to sunlight. I’m not describing an ideal data transmission environment here.

Ah, I’ve never looked into what hardware is actually available at the consumer level. That is a lot of money to move a video signal from one place to another.
FWIW I just looked at the AliExpress-tier options and they are much cheaper, but I don’t know about latency situation even if they do hit advertised bandwidth.
I didn’t even know HDMI cables went up to 15m for the copper version.
