Challenge

\r\nEver looked at your pet and thought, \"You deserve something awesome\"? Well, now\u2019s your chance to fix that! Design a tech-powered gadget for your furry (or non-furry) friend using Arduino and 3D printing. Think automated playmates, high-tech trackers, smart aquariums, or remote-controlled feeders. Whether it\u2019s a self-fetching ball launcher, a next-level scratching post, or a fish tank that runs itself\u2014you know what your pet needs.\r\n
\r\n
\r\nNever used Arduino before? No worries! Arduino is a small, programmable board that can control lights, motors, or sensors, and it\u2019s the perfect way to add some tech magic to your project.\r\n

Design a 3D-printable accessory or tool that makes your coffee corner even better. Whether you're brewing with an espresso machine, a capsule coffee maker, or hand-brewing every cup with precision, we want to see your best ideas. Maybe your espresso prep area needs an upgrade\u2014a tamping station, a sturdy knock box, or a better way to keep barista tools in order. If some tiny plastic part on your machine inevitably broke, why not design a replacement? Basically, if it enhances, organizes, or improves the coffee experience without touching actual food or liquid you will be consuming, it\u2019s a valid entry. Just remember one important rule: no food-contact parts (3D-printed filters, portafilters, or anything that touches hot liquids directly are a no-go).","isOpen":true,"openFrom":"2025-03-07T07:56:32+00:00","openTo":"2025-03-23T23:59:00+00:00","modelsCount":102,"winnerPrize":"500 Prusameters which are more than enough for one Prusament spool.
