How to make foldable Laptop Stand.( light and portable)- with cardboard.

I need a laptop stand that I can bring it along easily in my laptop back.
It has to be light and portable. so I come out with this simple laptop stand design that can be fold flat and place together with my laptop inside my laptop bag.
I hope this will solve the same problem that some of you might have.

Please watch the build video below on how to build it.

I build it with cheap material like cardboard and papers. but you can build it with more durable material of your choice.
Material needed:
- Cardboard box (cereal box)
- Wrapping paper (can change to something more durable like cloth)
- neodymium magnets ( watch this on where to get it https://youtu.be/pp1Dwx4AF3g )
- anti slip rubber strip.
- 502 superglue.
