Taking inspiration from the iconic Rubic's Cube, Ozobear is a puzzle you designed to appeal to kids of this generation. The 3D-printed creation by Emmanuel Carrillo is available for download online, made up of six interlocking blocks that rotate around a central pin. Since the toy pieces are designed to fit snugly against one another and rotate, it's advised that the printed pieces be smoothed out before assembly. Otherwise, no additional tools or fasteners are required in order to create this cute puzzle toy.
Since the bear toy is something that you can make yourself with access to a 3D printer, there's tons of opportunity to get creative with customization. Carrillo even includes a fun vinyl panda sticker set to give the bear one different personality option.
