I like to use this (Walmart but also available on Aliexpress and other places) lightweight and portable (charging) grip for my Joycons when I travel, but I actually prefer it over the regular flat square grip that I had before so I'm using it at home as well. So I made a stand for it that takes into account the angled position of the Joycons with this grip.

Simple print in any material you like, no supports required. Very little infill needed.
