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.
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)
