I broke down and bought a 3D printer several months ago. I didn't want to buy a trinket maker (though we've made our fair share of little toys for the kids). I really wanted this thing to be a workhorse to add to the toolbelt.
There's a ton of designs you can download that are useful. The library of "stuff" is practically endless. Example - here's a screw gauge I downloaded and printed.

This is similar a tool you can buy straight from Amazon, but there are some great custom things out there that are unique that you wouldn't otherwise have access to. For example, someone has redesigned a chute for my miter saw that dramatically improves the collected dust.
These uses are neat and all, but not living up to the potential, IMO. I think to really take advantage, you've got to learn to use 3D CAD. It's taken a little time and a lot of CAD-related Youtube videos, but I've managed to find some unique uses that have been very helpful. It's invaluable for making custom brackets (got to be careful about the material you're using) and gauging tools.
I've used it for things like making a set of plates for routing a mortise and tenon. My wife needed a custom stamp for a friend, and I was able to easily pop one out in 15 minutes of CAD work, and 2 hours of printing. A stamp like this might otherwise cost $50+ and take weeks to ship.

Most recently, I've been looking to add some built-ins to a room. I'm pretty picky about the details when adding cabinets to a room. I've used the visualizer tools, but I've never liked the result, or had confidence in the final look. So here's an area we're looking to add two desks with shelves:

Was able to design to exact dimensions in CAD:

And then - print a scale model!!

I'm pretty sure the wow factor won't translate in a picture - but it's helped me with what I needed to tweak our design and make sure it works with the space.
So if you've ever thought about a 3D printer, and you consider yourself a tinkerer, I'd say go for it. They're fantastic little tools for prototyping, and a huge range of niche capabilities. For those of you that have bought a 3D printer, what type of unique uses are you getting out of yours?
