I have to take my switch between a couple places quite regularly and my main carrying case is a little more aimed towards making sure it doesn't get damaged during longer travelling sessions and takes up quite a lot of place in my backpack. I designed this alternative "case"/cover so that I can just throw the console into my backpack and take a 20 minute bus journey while knowing that the screen and the joycons won't get hurt.
The cover attaches to the vents and holds the console firmly enough that I can confidently lift it up by the case and even shake it a bit.
In case anybody else has a similar requirement and a 3d printer, I posted the models here:
