A bracket that goes over the JoyCon comfort grip and holds the Switch above for a vertical layout. This provides better comfort than bare JoyCon's by utilizing the comfort grip, and makes the console narrower for better comfort if you play while laying down.
Both sides of the model simply clip on to the Comfort Grip/Switch Console, and are held together with an M4 bolt. The holes for the bolt are slightly undersized, the intention being for it to be threaded in. I've also added vents to the top so the consoles exhaust isn't restricted.
I printed both parts on their backs with 5 top/bottom layers and 50 percent infill, because the unit is top heavy I wanted extra strength. I also used tree supports for the longer overhang on the controller side of the model.
