I designed and printed this laptop raiser 4 years ago. I used it every day since, putting it in a bag multiple times a day. One day my pc reached 90ºC, it bent a little, and it's kinda wobbly if you don't use the bottom reinforcement. I can stand on the sides and they won't break (+80kg). More than 3500 downloads in other platforms.

I made this clothes hanger for my old folks flat. They have a small terrace, it fits perfect, and you can hang it close to the ceiling when not in use so it does not get in the way. It is fully customizable, as it size depends on how you cut the tubing.
