After printing all the wonderful controller stands for Playstation and Switch, I ended up with one particular ‘controller’ that didn't have an off the shelve printable stand. The JoyCon Grip Pro stand is very simple but does the trick. I did use a switch logo as a stamp.

Update: I added a v2, this one has extendible legs at the back as I noticed the old one could fall over when a charging cable was connected. With the new legs that won't happen. Also made the model a bit smoother. So ignore v1 and go for v2 immediately ;-) it's the profile that shows the two extra legs
