How to download multiple formats of a web font from the (official) Google Web Fonts repo?

Question

I've learnt that Google automatically serves TTF, EOT, WOFF, or SVG font files depending on the browser / device it's accessed from.

Now I am planning to host and serve the font files from my server itself, for which I would first have to download all the file formats of the web font(s).

How or where can I download the 4 file formats for a web font that I would like to use?

PS: By using different browsers -- Chrome, IE9 and Safari (dev - iPhone UA), I was able to get the WOFF, EOT and TTF formats. No luck with the SVG format though. It would be awesome if there's an even simpler way.

EDIT: Oh, and by the way, I do know that I can download various formats from fontsquirrel, but I am talking about downloading from the official repo here.

I made a tiny PHP script to get download links from a Google Fonts CSS import URL like: https://fonts.googleapis.com/css?family=Roboto:400,700|Slabo+27px|Lato:400,300italic,900italic

You can use this tool here: http://nikoskip.me/gfonts.php

For instance, if you use the above import URL, you will get this:

I got tired about updating this answer on each new release of Chrome, because they always change the way you can spoof the User Agent string, so please use this script instead.

======= OLD SOLUTION =======

Using DevTools from Chrome you can override the User Agent.

How to:

1. Get the font that you need at Google Fonts page.
2. You will get an URL to import in your CSS, like: http://fonts.googleapis.com/css?family=Cabin:500,700,500italic,700italic
3. Open that URL in your browser and you will see the full URL where you can actually download the font.
4. Go to Developer Tools (F12) and press ESC
5. Select "Emulation" tab and then click on "Network" sub-tab
6. Finally on Spoof user agent select IE9 for EOT format, Android 4 for TTF and this UA String for SVG: Mozilla/4.0 (iPad; CPU OS 4_0_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/4.1 Mobile/9A405 Safari/7534.48.3 (thanks anonymous)
