Here's an interesting little gizmo for the RPi, and very inexpensive. They do mention a caveat for the 3 though since the 3 relocates the LED and also the SD slot is no longer spring loaded. I've found this identical box under other names advertised for as much as $100 so $20 seems a bargain. I may just have to order one.
