Day 95 – Kinematics bracelet #2
Day 95 – Kinematics bracelet #2 640 480 mathgrrl

Yesterday’s bracelet was so great that we decided to print another one today, again from Nervous System’s Kinematics@home site. STL file: http://www.geekhaus.com/makerhome/day95_kinematicsbracelet2.stl (but go make your own instead of using…

Day 94 – Kinematics bracelet
Day 94 – Kinematics bracelet 640 480 mathgrrl

The design studio Nervous System has put up a great free morphing/algorithmic/supercool bracelet-making site at Kinematics@home where you can modify bracelet designs within certain parameters and then either download an .stl file…

Day 93 – Pig and Veg toothpicks
Day 93 – Pig and Veg toothpicks 640 480 mathgrrl

For the holidays, here are some toothpicks that you can use to label foods according to if they contain meat (bacon!), are suitable for vegetarians, or have some potential allergen…

Day 92 – Weeping Angel from Dr. Who
Day 92 – Weeping Angel from Dr. Who 640 480 mathgrrl

Great, now we’re too terrified to take this out of the printer. This beautiful and horrifying model is fantasygraph’s Dr. Who Weeping Angel on Thingiverse. We printed it in honor…

Day 91 – Truncated Icosahedron
Day 91 – Truncated Icosahedron 640 480 mathgrrl

We didn’t have time to make this one earlier, so here it is now. A truncated icosahedron (Buckyball/soccerball/football depending on who you are). I made the snaps really tight so…

Day 90 – Stellated Octahedron
Day 90 – Stellated Octahedron 640 480 mathgrrl

And finally, the last of the set of models from my entry to the Makerbot Academy Math Manipulative Challenge on Thingiverse. This model shows that we can use the individual snap tiles to…

Day 89 – Icosidodecahedron
Day 89 – Icosidodecahedron 640 480 mathgrrl

Today, the simplest Archimedian solid using triangles and pentagons, the icosidodecahedron: STL file: http://www.geekhaus.com/makerhome/day89_icosidodecahedron.stl Tinkercad link: https://tinkercad.com/things/9rjPDpql1vO-tiles-for-icosidodecahedron Thingiverse link: http://www.thingiverse.com/thing:185859 Settings: The tiles are optimized to work with the low/.3mm MakerWare setting…

Day 88 – Truncated Octahedron
Day 88 – Truncated Octahedron 640 480 mathgrrl

Yesterday’s model was the simplest Archimedian solid with square and triangle faces. Today we have the simplest semi-regular polyhedron with square and hexagon faces, the truncated octahedron: STL file: http://www.geekhaus.com/makerhome/day88_truncatedoctahedron.stl Tinkercad…

Day 87 – Cuboctahedron
Day 87 – Cuboctahedron 640 480 mathgrrl

To get more flexibility constructing polyhedra we can use individual snap tiles instead of pre-arranged hinged nets. This also allows us to make nice two-color semi-regular polyhedra, such as this…

Day 86 – Rectangular Rhombohedron
Day 86 – Rectangular Rhombohedron 640 480 mathgrrl

The last of the polyhedral nets so far is for a rectangular rhombohedron: STL file: http://www.geekhaus.com/makerhome/day86_rhombohedron.stl Tinkercad link: https://tinkercad.com/things/4QmyBzqKqlL-hinged-rhombohedron Thingiverse link: http://www.thingiverse.com/thing:185859 Settings: Low/.3mm MakerWare settings on a Replicator 2 in one hour…
