Raspberry Pi Model Railroad Camera Car - Track Power and Swivel Mount

I posted a picture of my 3D printed Raspberry Pi model railroad camera car to Mastodon and Twitter yesterday.  The Raspberry Pi official account retweeted it while I was asleep and I woke up to a lot of likes and views and people asking for a video.

I figured I'd show off the project and the improvements I've made since the original design in the video as well, so it got a bit long.  I'm not at my parents' house so I don't currently have access to our full layout, so I got some EZ Track, an Arduino running DCC++ EX, and a Raspberry Pi running JMRI to put together a test track.

The car is 3D printed and based on this model I found on Thingiverse:

I did some tweaks to the model both in software and by drilling holes in it after printing to cobble together what I showed off in this video along with making some of my own 3D parts in Blender (namely the pulley wheels, pegs, and camera mount).  I also used a Raspberry Pi Zero mount I found here:
