Today we printed owens’ Diagonal Cut Menger Sponge design from Thingiverse. If you sliced a Level 2 Menger sponge in half along a diagonal plane as shown in the picture,…
To finish our collection of trefoil conformations, we have a stick knot and a cubic lattice knot: STL file for stick: http://www.geekhaus.com/makerhome/day153_trefoil_stick_40_25.stl STL file for lattice: http://www.geekhaus.com/makerhome/day153_trefoil_lattice_40_25.stl Thingiverse link: http://www.thingiverse.com/thing:234107 Technical…
Two more trefoil conformations – as a petal knot (all crossings line up along one center stem) and a tight knot (with the smallest amount of rope length possible given…
Continuing our collection of trefoil knots, today we printed a trefoil in a Fourier-(1,1,2) knot conformation and a trefoil knot in a tritangentless conformation. In other words, the first trefoil…
For the next four days we’ll be posting various mathematically interesting models of the trefoil knot. Mathematicians consider two knotted forms to be equivalent if one can be transformed into the other…
The semester has begun and we are back to teaching calculus. Later this semester we will cover Volumes of Solids of Revolution with the “disc method” and the “shell method”,…
Does it count as a print-a-day print if something I designed and sent to Shapeways was delivered today? I think it does, at least the first time it happens! Our…
My son loves pi. The number. He and a friend at school have actual arguments about who has memorized and/or written down the most digits of pi. The other day…
Henry Segerman is well-known for the intricate mathematical modeling that he designs and prints at his Shapeways shop. So to put our Replicator 2 to the test, today we printed…
More TopMod! Today we made a knot: STL file: http://www.geekhaus.com/makerhome/day137_cloverknot.stl Thingiverse link: http://www.thingiverse.com/thing:224032 Settings: MakerWare .15mm/high with raft and supports, in 6 hours and 23 minutes. I didn’t use the custom knot…
