This is a stylish laptop stand that allows you to use the computer at 4 different angles but also allows you to completely fold it for easier storage and transportation.
Print two pieces and place them underneath your laptop.
You can print this in a 235mm bed size printer (Ender 3 style), by turning of the skirt/brim and rotating the piece 45 degrees. (Check last picture)
To make sure print will come out nicely at first try, I advise you to calibrate the flow of your filament and also make sure you don't have too much elefant foot! If you're unsure of any of these things, just google “Flow calibration” or “Elefant Foot compensation”, it should explain everything you need.
