In couple days we will get Nintendos own phone app that you can use to chat (and do all other cool stuff) with your friends while playing Switch. So I made this mount for your phone so you can see your app when you play your games in handheld mode. It should be easy to modify the phone mount to your phones measures, if you have some other phone than Samsung Galaxy S7 (phone mount part is measured for Galaxy S7).
I did put some padding to upper part of Switch Part so it's really tight fit, and I have to say that this will be great to have when playing games like Splatoon 2 :)
Phone mount dimensions are about:
142.4 x 69.6 x 7.9 mm (5.61 x 2.74 x 0.31 in)
Just print both parts and glue them together (phone mount and upper switch part) and it should hold your phone well (could work without glue I guess..). I will use Power Flex super glue. Lower part (Switch Parts) will go together with two M4-0.7x20mm screws.
