These legs lift your original-style PlayStation 4 off a surface, increasing airflow under the device and allowing storage of a game case or maybe a notebook should you so desire. They slide snugly onto the sides of the playstation.
I used superglue to attach solid non-slip toolbox liner from Harbor Freight to the bottom. Cut slightly large, glue around the edge of the leg and some in the center. Allow to dry, then trim with an xacto knife by placing the leg upright (liner-side down) on a surface, and cutting around the edge, angling the blade slightly underneath the leg. This gives a clean, neat cut.
NOTE: You may have to scale slightly depending on your printer and slicer. You should only have to scale in the height (y-dimension as I orient them). The legs should fit snugly without forcing them.
