The IKEA's Frosta Stool Hack is absolutely brilliant. It takes the ready-to-assemble furniture piece and turns it into a wooden training bicycle for children. The design was inspired by a blog post written by Ray of Core77. In it he addresses two separate designers who have tackled DIY projects and their complementary assets, he writes challengingly, "We'd love to see you guys collaborate on a series of IKEA hacks with bespoke 3D printed parts and instructions."
The two artists, Andreas Bhend and Samuel Bernier took up the challenge to create the IKEA's Frosta Stool Hack. Although they have never met, Bhend made the trip from Switzerland to Paris and the rest is history. Using only pliers, a drill, a metal saw and a 3D printer, they put together an impressive guide to a fun project.
