I just improved an existing design of 3D-printed Switch portrait grip. The result is quite good. You can now play portrait games perfectly (if you have a 3D printer or know someone who has a 3D printer).

Also a complaint: switching to portrait mode is a pain in Retroarch. The only way is to enable Advanced Settings in Interface, then change the system-wide Video setting, then reload the Core. PFBA is much better with rom-specific settings of screen rotation and can be changed on the fly.
