This is a lamp shade that is designed to turn a IKEA lightfixture named Rodd into an ambient light. It is a wall/uplighter an is designed for 10-20 watts fluorescent lightbulbs.Rodd- Hat Building instruction Two materials should be laser-cut: 3mm plywood and 3mm opaque acrylic or polystyren. After cutting you have 3 pieces of wood and two pieces of plastic. Attach the two pieces of plastic in the slots of the middle wood section. Glue them together in such a way that the front is in line. Now glue the bottom woodpiece to the contraption. Finally glue the top/front piece to the construction en let it all dry. I advise a 10 to 20 Watts fluorescent lightbulb, please do not use a classic lightbulb due to the heat in short distance from a flammable wooden cover.
