The bidirectional frame that intersects missed is so thin that it seems very weak, but in fact it is very strong as it is entangled and swirled mutually in opposite direction. This structure uses less materials, while has less transformation by impact and force from several angles. Also this structure has a wide space among frames, and by allowing the heat to be easily discharged to this empty space it will not be transformed by the heat of illumination.

The interior lighting fixture was made to be easily produced by combining it with cheap lighting part that you can find from around, and repaired. However, you must use only LED bulb, because the common light bulb can be transformed as it emits lots of heat.

It was divided in small size by considering the maximum printing-out size of common desktop FDM 3D printer for more people to have this lighting fixture. Therefore, anyone who can have 3D printer or who can use it, though it is not an expensive 3D printer, can print it out.

It was designed for printing out with a low-priced FDM 3D printer, and to obtain a clean output without a post-process.

The size of this Light is of 240mm (diameter) and 200mm (height).
