Pi Camera Stand Box for Pi Camera Module 3

This updates the box of https://www.thingiverse.com/thing:4251362 with an additional cutout to better accommodate the larger lens module on the Camera Module 3.

To print a stand, you'll want to replace Box.stl from https://www.thingiverse.com/thing:4251362 with Box-v3.stl from this thing and then print the rest of the parts as-is from that thing.
