I have been converting my tripods to the Arca Swiss system and came across an L bracket on the bay that is a custom fit for my D3200. This allows you to change batteries and access all ports without taking it off. It also would protect your body from impact. Beautifully made for under £20 UK. Great for landscape to portrait in a hurry.

@Haggis, can you link to the D3200 specific one?

Similar QR adapters can be gotten quite reasonably, and more or less generic L brackets, but it's a bit harder to find one that's specific to the D3200.
A generic l bracket does not do this.
You should be able to get this one on the bay or Amazon.
