For this weeks assignment I chose to design a "Spinning top".
I designed it using Rhino, and the file can be download here Rhino & STL.
For milling it we used the Modela.
There are 2 drill bits to use 1/8" hard or fine.
First I used the hard to mill as much as it can and then I used the fine one to do a smoot finish.
I used this tutorial mill the wax I had.
The finall cutting result:
I used silicone rubber and the instructions how to make it are here:
The ratio of the mix is 100A : 10B.
This are the materials (part A and B).
I poured water inside the mold to know what is the level of the material to mix and than i weighed using the scale.
I had 160gr of Material A so i added 16.gr of material B and mixed it for about 10 minute untill i got a unified mesh.
This is the what I got:
And the final result:
