Laptop vertical stand (for the Huami Redmi G 5P)

For the grooved version, you can buy some velvet fabric and cut it into 1.75cm*18cm and 1.8cm*2cm strips to stick to the grooves. For the non-grooved version, you don't need to stick anything. If you're worried about slipping, you can buy four 18~15mm round foot pads and stick them to the bottom.

It works with the ASUS ROG Zephyrus G15/G15 Pro, I don't have other laptops to test whether it fits other models. The size is 19mm, you can measure your laptop to see if it fits.
