Carbon is a snap-together construction set of hexagons, pentagons and connectors to build open and closed 3-dimensional surfaces from 1mm thick styrene.
Details of the connectors are highlighted when a Carbon capsule is used as a low-wattage lamp shade (pictured) on a table lamp. A type "T" 25-watt bulb fits into the capsule easily. Avoid larger bulbs or higher wattages to prevent warping or melting the styrene.
The eps file carboncapsule.eps contains enough pieces to build the lampshade, plus a few extras. If designing your own set of pieces, be sure to keep the part edges at least 5mm apart on your layout. See photos for alternate views of the assembled capsule and some illustrations on how to assemble the connectors and polygons.
