Contest theme: Back to school 2025

The school bell is about to ring, and that means it’s time for the Back to School Flash Contest! Last year’s round was a big success with loads of useful entries, so we’re bringing it back again this year. Design 3D-printable tools that make school life easier: a timetable board to keep track of classes, math and science helpers like geometric sets or molecule models, flashcard boxes for quick study sessions, or space-saving gadgets for lockers and backpacks. Whether it’s for elementary school, high school, or university, we’re looking for classroom-friendly, practical designs that students can actually use.
