Where to put downloaded custom models?

[Potassium]

I downloaded some custom models to put into my map, but I don't know where to put them.
Specifically, these ones.
Printer
Card Reader
Mikros Office Pack
Mainframe Computer
I have unzipped the files but still don't know.

You want to put them in a folder under your tf folder called "custom"

the format should look like this

├── tf
│   └── custom
|        └── < any folder name here >
│           ├── models
│           ├── materials
│           └── particles

Attached are what my custom folder looks like

I now have the models, but the materials show up as missing. This is the inside of my materials folder. Also, thank you
