Do you use 3d printed mounts?

What teams use 3d printed items to make mounting easier/take up less space? stuff like this:

If so, do you think it makes these sort of things any easier? Which electrical components do using these improve most upon? Are the examples above the type of thing that you use? If not could you please leave a link to what you use? I'm looking into finding mounts and stands that can best make use of space in case we have another low bar predicament. Thank you.
