I always find the icosahedron the most difficult polyhedron to assemble with modular tiles. It is so close to spherical that the angles make assembly difficult; putting something together on…

Our fifth Poly-Snap example is the Icosidodecahedron, a semi-regular polyhedron with twenty triangles and twelve pentagons. It’s sort of like a mini-Buckyball with triangles in place of the hexagons. Today’s new…

A “snub polyhedron” is a model obtained by adding triangles between the faces of another polyhedron. For example the Snub Cube below is like a cube whose six square faces…

Our second Poly-Snaps model is an Octahderon, with eight triangular faces. Compare with the Hinged Octahedron from Day 82, which is beautiful and prints in one piece, but has variable…

Over the next six days we’ll be posting polyhedra that we assembled using our new Poly-Snaps on Thingiverse. Our previous polyhedral models were made from Snap Tiles which had either two or three…

I like the rounded and nicely-spaced design of 3DAndy’s Pentominos on Thingiverse, but wanted to print some tetrominos instead, for math/puzzles (for example, polyomino packing problems) and for future Tetris-related art…

This is a model of the building that houses the MakerBot Headquarters in Brooklyn, with a hole in it for a couple of pens or whatnot.  The basic building shape…

Today’s print is a knot with a special property: No matter how the knot sits on the table, it never touches the table in more than two places. This property…

This design was inspired by DesignMakeTeach‘s excellent post Sharpie to 3D Print in 30 Minutes on his blog designmaketeach.com. Such a fantastic idea for introducing someone to 3D printing and for…
