Umukino w'Kubaka RenyiTong ni igikinisho cyo kubaka gikozwe mu byuma bifatanya bisa n'imizingo idasanzwe (three-dimensional circle connectors). Iyi seti ikoresha ibice bitandatu byibura. Buri gice gishobora guhuzwa mu muzenguruko kugira ngo hakorwe ishusho y'ibice bitatu. Ibice byinshi bishobora kandi guhuzwa hamwe kugira ngo hakorwe imiterere y'ibice bitatu igoye kurushaho. Uduce two guhuza ibice (column holes) dukoreshwa mu guhuza ibice hamwe. Igishushanyo cyahumekewe n'ihame rya Tai Chi n'akadomo ka Mobius (Mobius strip), byombi bisobanura imizenguruko idahwema. RenyiTong ikorwa hakoreshejwe uburyo bwa stereolithography 3D printing. Iki gikinisho gigenewe gukoreshwa mu burezi ku bana n'abakuru.
