You can also think about tools that could help someone master a new hobby or finally figure out how that complicated gadget actually works. A well-designed submission could help a child understand basic science principles, assist a university student in visualizing complex engineering concepts, or aid professionals in improving their skills. Think creatively and consider learners of all ages and fields. The winning entries will likely combine innovation, practicality, and that special touch that makes learning feel like an adventure.","isOpen":true,"openFrom":"2024-10-02T12:35:42+00:00","openTo":"2024-11-02T23:59:00+00:00","modelsCount":134,"winnerPrize":"Original Prusa MK4S Kit! and Prusameters","entryLink":"https://blog.prusa3d.com/contest-education-tools_102903/","winnersLink":"","printDateValidation":"2024-09-12T00:00:00+00:00","signedModelsCount":null,"maxModelsPerUser":5,"__typename":"CompetitionType"},{"id":"454","slug":"scratchers","name":"Scratchers","teaserImageFilePath":"media/competition/teaser_images/454/small_banner_drbatka.jpg","description":"Got an itch to create something useful? Our latest flash contest, \"Scratchers\", is your chance to design 3D-printable back scratchers, head scratchers, and body scratchers that not only soothe but also make everyday life a bit more comfortable. Your designs could help people with mobility issues, provide a moment of relief during a hectic day, or become the go-to tool for relaxation at home. Whether it's a telescopic scratcher for reaching between shoulder blades (or your dog's favorite spot) or an ergonomic tool for those with limited range of motion, we want to see your most clever and practical ideas.","isOpen":true,"openFrom":"2024-10-04T05:17:12+00:00","openTo":"2024-10-20T23:59:00+00:00","modelsCount":55,"winnerPrize":"400 Prusameters which are more than enough for one Prusament spool.

Our latest flash contest, \"Single Extruder - Dual Color\", challenges you to create an illusion of two-color prints with a twist! We're looking for designs consisting of two separate printable parts that interlock to create a dual-color model (both parts must be printable on a single extruder printer). For inspiration, check out maker Rossero, who has created several popular models using this technique, and we absolutely love it! Our contest's hero model, the Single Extruder Dual Color Dutch Cow, showcases exactly what we're looking for - a design that combines two separate prints into one clever dual-color piece.\r\n
\r\n
\r\nJUST REMEMBER, WE'RE NOT AFTER MULTI-MATERIAL PRINTS OR DESIGNS THAT REQUIRE FILAMENT SWAPS.\r\n
