Kumiko Lamp - FILES ONLY!


Instant Digital Download

I'm inspired by Kumiko and Shoji craftsmanship from Japan - “Kumiko”, in short, is a delicate technique of assembling wooden pieces without nails.

(Thinly slit wooden pieces are grooved, punched and mortised, and then are assembled and joined one by one with a plane, saw, chisel and other tools while fine adjustments are made. The “Kumiko” woodwork technique was developed in Japan in the Asuka Era (600-700 AD) and has since been refined and passed down through generations of craftsmen.)

You can purchase beautiful handmade Kumiko lamps on Etsy, but they'll cost you, and rightly so, because of the amount of effort, skill and craftsmanship required. Here's a fine example: https://etsy.me/2CIQJpj

However, I'm offering a much less expensive alternative. For that reason, I've mimicked the style with my own design, but 3D-printed! And you can print them yourself!

I wanted to be free of screws and other hardware, true to the design ethic of Kumiko, so the lantern snaps together and can be taken apart easily. The socket and some other touches, such as the nylon clamps for the cord, were unavoidable, but ultimately I'm striving for a sustainable design lifecycle approach. The plastic is PLA with 30% wood fibre.

Because there will be no glue use or screws to fix the lamp together, parts are designed to fit TIGHT. That means you might need to sand in some places. And you'll need a few supplies to complete the lamp (You can substitute with more accessible variations, but remember, all DIY electrical work is done at your own risk and Seigi Designs accepts absolutely no liability for injury or damage.)






There are two base variants, one for a standard medium socket and one screw-in base with tool for battery-powered LED lantern lights. See photos.

IMPORTANT NOTE: The lamp is meant for accent lighting and is not intended to be a sole source of light - it uses a 25-watt equivalent LED light. Please don't use incandescent bulbs in this lamp!
