In 2008 Haruki Nakamuri produced this stunning piece of papercraft for the World Contest. Now he has made the patterns and manuals for construction available for download. The price is $40 usd and purchase can be made through PayPal. Once your payment has been received you will be provided with a download link for the documents.

The English manual has been converted from the Japanese and I am still attempting to improve it, but it is understandable and the pictures speak far more than the words anyway.

This is a challenging piece to assemble so if you are unsure if you could make this, try the free trial pattern below first.

Unfortunately the delivery process has a manual step, once your payment has been received the the plans will be emailed to you as soon as possible.


The smallest gear from the gear globe is available as a free download. If you can make this piece then you should be able to make the rest of the gear heart.
