This is another moving geared thing, joint work with Saul Schleimer. The three pins can move against each other, but must all move together - no one pin can move on its own.

Borromean hairpins is also available at Shapeways.

can you make a version that is one alone thx

does it need supports?

I'd recommend doing it with supports. If you have issues with your supports sticking you might want to play with fixing that before trying this print because it is a pain to clean up the gear faces.

Hi henry.

Thanks alot for putting amazing models like these online for everyone to enjoy and to learn from. I have seen your video's and they are quite inspiring. Keep up the good work!
Printing this tomorrow.

Best regards,


Anyway to get this made into the "rings"? Interested in printing on a connex machine!

You mean closing off the ends of the hairpins? I could make a version like that, but I would be very surprised if it would print without being fused together in the middle.
