P wanted something for his office and it is AWESOME. Forty rhombic dodecahedra of awesome. Printed from emmet’s Dodeca Chain Loop on Thingiverse. Thingiverse file: http://www.thingiverse.com/make:50382 Settings: MakerWare “standard” with no…

Today we used Tinkercad to design 2D nets that fold up to regular 3D polyhedra, specifically the tetrahedron, octahedron, and icosahedron which all have triangular faces. STL file: http://www.geekhaus.com/makerhome/day44_triangularnets.stl Tinkercad…

The problem with Day 29’s Icosahedron Failure Bowl wasn’t with the model, it was with the machine. Turned out that the Replicator 2 needed a new xyz motor wire harness.…

It’s hard to 3D-print a Level 3 Menger sponge.  But it isn’t hard to print a slice of one, and it makes for a decent coaster. STL file: http://www.geekhaus.com/makerhome/day23_mengercoaster.stl Tinkercad link: https://tinkercad.com/things/kETD0Hz44gY-day-23-menger-coaster…
