Description

This piece is designed to have 3mm dia magnets embedded in its side. When several are printed they can be assembled into a gyroid shape.

The sample was printed in a Stratasys BST-768. I'm not really sure how this would go on a MakerBot.

Instructions

Each gyroid block requires 12 magnets (be careful to install them with alternating polarities.)

The 3mm dia x 3mm long magnets can be found at Gaussboys. Product #C0303. They are about $0.08 each.

I made a bunch of these for the 3D Printer Village at the NY Maker Faire last week. Kids loved them! Some kids came back to play with them three times.

This would be a great toy to sell at science museums!

after putting them together on my computer, i noticed there are some triangles left open. Could you fix that too please. Otherwise it's a great addition!!!

Hi Matei,

I just realized that the open triangles you're looking at may not necessarily be a mistake (though, I'd agree, they're not desirable.)

The triangles occur at the corner intersections of the blocks; they are just a consequence of having to split the gyroid shape into cube-nested shapes.

Thanks for the kind words! It's just the standard Stratasys blue plastic.

This is a really nice design... Are you familiar with Erwin Hauer's modular blocks from the 60's?

Also, where can we get that indigo blue plastic?

Ohhh, Erwin's stuff is awesome! I wish I could do that.

yes that indigo is very nice indeed.. is it selfmixed?

that is super cool!

This is awesome, but I only see one set of magnet holes in the STL. Can you fix it?

yes, sorry! I just realized this is not the up-to-date file. I'll get to that.

could we design our own large stepper motor where we put magnets at the circumference of a large disc and then control everything with electromagnets?
