I am thinking about buying a 3d printer but I have no idea what I would do with it. I did some blender training and made a donut but it did not really inspire me.

I browsed thingverse and some other sharing sites. Nothing really caught my eye.

I think something that would are mechanical kits for making gears or small machines etc. Printing a mechanically true LS1 V8 for example kind of interests me.

Any thoughts to share?
