Make Furniture With Cardboard! Cardboard Chairs 101. There are two basic ways to resolve the structure problem: an interweaving, carton-like grid of sheets, or laminating a massive amount of sheets together and carving out a chair shape.

Cardboard Chairs 101

The latter solution is the most common one (see Frank Gehry). However, I think it's kind of a cheap way out, because you are not forced to deal with the actual properties of the material. It also makes for a lot of cutting, a lot of cardboard, and a very heavy finished product. This first chair is actually made from corrugated plastic campaign signs, held together with hot glue and epoxy. Campaign signs have great potential for Pop-Art designs. The second example is pure cardboard. Cardboard Desk Lamp. I started by designing a 3D model of the lamp using Autodesk 123D, which is freely available online.

Cardboard Desk Lamp

To make a cross section of the lampshade, I used the Draw tool and the 3-Point Arc tool. Notice the grooves on the inside of the lamp; they're carefully sized to hold the electrical lamp components in place once the lamp is assembled. Everything else was just roughly estimated and tweaked as needed. To turn the cross section into a 3D object, I used the Revolve tool. This tool spins a profile around an axis of your choice, producing an object with rotational symmetry. I made the stand using a combination of hand-drawn splines and hemispheres, adjusting it until it looked sufficiently lampy. I joined the two parts together using the Combine tool (set to Join mode), then exported the object as an STL file.

123D Fab! Cardboard Construction Kit. This is the story of how I designed a cardboard construction kit and how a bunch of very clever people at Autodesk University 2011 used it to make things far cooler than I could ever have anticipated.

123D Fab! Cardboard Construction Kit

I'll discuss the backstory of the construction kit, my thought process in designing it and what happened when it was unleashed on a test audience of designers, architects and engineers. The kit itself consists of an assortment of laser-cut cardboard pieces that can slot together in a regular, geometric fashion to form complex and weird structures. While the simplest components of the kits are just circles with slotted rims, the kits also contain a wide variety of decorative pieces (e.g. wings, hands, mustaches), mechanical components (e.g. wheels, gears, levers) and structural units (e.g. long beams, "peanut" shapes, semicircles) which can all be combined in countless ways. Here's one example of something that can be made with the kit, which is now available on the Instructables Store:

- You will need A LOT of cardboard for this project unless you are lucky like me and find some quadruple-layer cardboard lying around. Glue - I used Gorilla Glue and suggest that you use the same. Build a Frabjous. Geometric Sculpture of George W. Hart, mathematical sculptor. George W.

Geometric Sculpture of George W. Hart, mathematical sculptor

Hart As a sculptor of constructive geometric forms, my work deals with patterns and relationships derived from classical ideals of balance and symmetry. Mathematical yet organic, these abstract forms invite the viewer to partake of the geometric aesthetic. I use a variety of media, including paper, wood, plastic, metal, and assemblages of common household objects.

Classical forms are pushed in new directions, so viewers can take pleasure in their Platonic beauty yet recognize how they are updated for our complex high-tech times. Because my works invite contemplation, slowly revealing their content, some viewers see them as meditation objects. This page shows some of my own favorite pieces.
