This is a foot that replaces the short foot that comes with the Versa H17 computer case. This foot is 1.6 in / 40 mm tall. Perfect for letting your PSU breathe if your computer is in a small space on or carpet.
The inside is hollow and follows essentially the same design as the OEM foot, except it is a bit thicker for strength. I printed mine in black resin, but I'm certain any FDM print will work perfectly.

When I made this a year ago, the Versa H17 was the only cheap microATX case on the market that didn't have the dumb tempered glass. I recommend this case if you would like your computer to not break when you move it. The price has also gotten lower since I bought it two years ago.

From Versa: "Designed for entry-level PC builders and gamers, Thermaltake Versa H17 Micro Case features the simplicity appearance with easy cable management design, AIO liquid cooling compatible, and ample ventilation options. Good choice for those who opt for stylish PC case with manageable frame size and advanced features."
