This is a fun one. Here's the link https://fonts.google.com/specimen/Trispace
It's disappointing how few styles (8) are shown in the Google Fonts view. It definitely feels like an injustice to the amount of work done on this typeface. If you click that nice DOWNLOAD FAMILY button in the upper right corner of the page you'll get a convenient folder with the variable TTF file and a static folder with 40 STYLES. 8 weights across 5 widths. 8x5=40.
So please, go make awesome stuff. And by all means, submit your designs to http://fontsinuse.com
