Joy-Con Grip Moto Mod

Since Nintendo came out with their voice chat app I wanted to make a grip that can hold my phone. Decided to use magnets to create sort of a Moto Mod for the Z series phones.
It uses 4 8x3mm cylindrical magnets to hold the phone in place. To attach the Joy-Cons I took the rails off of the grip that came with the system. I had to pre-drill holes so I could screw the rails in place.

Enjoy!

Update 1-22-2018: Added a small indent for the power/lock button and made the guide pin smaller. MotoM
