The file 'Gyroid Magnetic Assembly Block 3D Printer Model' is (stl) file type, size is 775.7KB.
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.
