Part of the fun of 3D printing is discovering just how many possibilities there are for different things to print. Obviously, they're fun for printing toys or decorations that you couldn't or wouldn't buy yourself, but they're also powerful problem-solving tools. Once you've solved a few problems with 3D printed parts, you start looking around for other minor inconveniences or quality-of-life upgrades that you could solve—and the breadth and depth of the 3D printing community means that you can almost always find someone else who has already thought up and posted a solution for you.
As a coda to our series about breaking into 3D printing for the first time, the 3D printer-pilled among the Ars staff is sharing a few of their favorite unexpected prints, from fun all-purpose gifts to containers and organizers to parts that will help you with your other, non-3D-printing-related hobbies. This is just a fraction of what's out there, but if you're still on the fence, maybe some of these will open your mind to the possibilities.
Coffee gear
Every morning, I make either a pour-over coffee or some form of espresso. For measuring my beans, I printed two dosing cups. The black one is matte black PLA with a fuzzy surface texture (an option in most slicers that adds random noise to the outside wall paths), and the white one is ABS that I sanded to a smooth surface. For sanding, I prefer ABS, as it’s easier to get something that has no real signs of layer lines. To tamp my espresso grounds, I printed a handle in black ABS and sanded it smooth to feel good in the hand. The rounded knob helps me get pressure more comfortably than the raw metal of the original tamper, and the radial fins fit perfectly into the dosing cup, keeping the tamp straight up and down so I don’t end up with a sloped surface.
