About this 3D model

just a strange shape i find aesthetically pleasing to the eye. you can just hang it by the hole as ornament... for everyday or just X-mas ;p with a twist to it. there is a mechanism in the shape, think hard enough, you will figure it out. don't panic, it's legal. at least no less then an average clockwork or kitchen knife. but if somebody over interprets my local law even 4 joined circles may be considered dangerous and require a permit this must be corrected. details will soon come on HUKACZ
