I make gimbal keychains for most holidays as a fun "business card." They're great small pieces that can easily show off some of the things you can do with 3D printing.
Here's the one I made for the 2019 winter holiday season!
This prints as one single piece and as an added bonus the raised name on the side works great for embossing and stamping.
I typically use the beaded metal chains for the keychain part, specifically this one https://amzn.to/3PDX4YD (affiliate link)
