Day 123 – “Ticket to Ride” card holder

Day 123 – “Ticket to Ride” card holder 640 480 mathgrrl

A couple of days ago on Day 120, we printed some train trays for the excellent game Ticket to Ride. That was all well and good until the cards seemed…

Continuing from yesterday, here are the other four interesting slices of a Level 3 Menger Sponge: STL files: http://www.geekhaus.com/makerhome/day122_mengercoaster5.stl (and 6 and 7 and 8) Tinkercad link: https://tinkercad.com/things/auZS4Sd7vIe-day-122-menger-coaster-set-part-2 Thingiverse link: http://www.thingiverse.com/thing:213053 Settings: Like yesterday,…

Day 121 – Menger Coaster Set, Part 1

Day 121 – Menger Coaster Set, Part 1 640 480 mathgrrl

Following up on Day 23‘s Menger-sponge-slice coaster, today we print four different slices of a Level 3 Menger Sponge.  There are four more interesting slices that we’ll print tomorrow. These were…

Day 120 – “Ticket to Ride” trains tray

Day 120 – “Ticket to Ride” trains tray 640 480 mathgrrl

C’s grandma gave us the game “Ticket to Ride” today, and it is great fun! The turns go by really quickly, making for a quick game that is fast-paced enough…

Day 119 – DSi Stylus Holder

Day 119 – DSi Stylus Holder 640 480 mathgrrl

C recently finished saving up for his Nintendo DSi (see Day 18 and Day 19 from way back in September), and apparently it is necessary to have multiple styluses (styli?) so that…

Day 118 – Poly-Snaps Icosahedron

Day 118 – Poly-Snaps Icosahedron 640 480 mathgrrl

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…

Day 117 – Poly-Snaps Icosiodecahedron

Day 117 – Poly-Snaps Icosiodecahedron 640 480 mathgrrl

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…

Day 116 – Poly-Snaps Snub Cube

Day 116 – Poly-Snaps Snub Cube 640 480 mathgrrl

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…

Day 114 – Poly-Snaps Octahedron

Day 114 – Poly-Snaps Octahedron 640 480 mathgrrl

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…

Day 113 – Poly-Snaps Truncated Tetrahedron

Day 113 – Poly-Snaps Truncated Tetrahedron 640 480 mathgrrl

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…
