I needed something to raise my notebook from the desk to improve cooling, after searching on thingiverse I found this two designs (thing:2742574 and thing:1723311) which were compact and effective, I have just created a similar object to fit my needs.
I wanted it to be compact, easy to use and to be able to set two different angles.
As you can see from the pictures there are two different parts which are one the mirroring of the other, you can change the angle of your laptop by just switching them!
I also included the .f3d file in case you want to modify it.
You may need some sanding in order to be able to attach the two parts togher (or you can also increase the diameter of the hole in Fusion360 using the provided .f3d file).
UPDATE: I applied some electrical tape on the bigger ends since it was too slippery on my desk, it is not the best solution but I couldn't find anything better. If you have some ninjaflex filament you could try printing a shell instead of using tape. If you do so please share it.
