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: Image
Some CAD and a 3D print later I have the solution no money can buy. That’s the power of 3D-printing and modeling.
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?
Water won’t get there and if the entire house is flooded and the walls are wet.
Fire protection is up to code.
If you would want to specify this (commercial installation) you likely would need to explicitly allow its use as this shape is not in the ISO/DIN standard.
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.

Going to wager those are significantly more flammable that the original material. Probably alright for purely low voltage applications. But not someone to take lightly.

UL94 V0 filament is available: PLA, PETG, ABS, PC and probably more.
V0 means stops burning within 10 seconds and no dripping. That’s good enough for these applications.

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)
