Thingiverse Holiday Ornament Challenge Closes with Filament Prizes

MakerBot’s Thingiverse wrapped its Holiday Ornament Challenge on December 31, 2025, drawing hundreds of seasonal designs from the community. The contest required entrants to upload a 3D-printable ornament file in STL format, provide photos of a finished print, follow originality and intellectual property rules, and tag entries with #Holidays2025. Winners are scheduled to be announced on or before January 14, 2026.

The prize structure focused on raw printing materials, with first place awarded a 10 kg Polymaker filament bundle and second place receiving 5 kg of filament. Prizes continued down to tenth place, with filament spools for those runners-up. Judging criteria were creativity, printability, and photography, and official rules covered eligibility, entry windows, judging methods, and logistics for claiming prizes.

For entrants, the immediate practical step is to monitor account notifications and the contest announcement timing through mid-January. Confirm that your submission included the required STL and finished-print images and that the #Holidays2025 tag was applied correctly. The contest rules included instructions for claiming prizes, so be ready to follow any verification steps or eligibility checks that organizers may require.

The contest mattered beyond the competition itself because filament prizes directly support additional printing for education, classroom projects, and community workshops in 2026. Educators who entered classroom designs and makers who submitted original ornaments may find the reward extends project budgets and enables further prototyping. The emphasis on printability in judging also highlights practical design considerations: models that print reliably and photograph well gained an edge.

Looking ahead, keep an eye on the January 14 deadline for winner announcements and prepare any documentation required for prize claims. Whether you entered or watched, the event underlines a seasonal pattern of community-driven design sharing and material-focused prizes that help fuel hands-on projects into the new year.
