Miserable Bear
Inspiration
 |
I found that lots of people put a sticker or tape on their laptop's camera for security reason and I thought that it would be cute/fun to put something on it which is better than the boring tape.
CAD model

 |
 |
I designed the CAD using Fusion360 and modeled the mold as well by slicing the bear part in a half to make two pieces of molds.
Milling the wax molds
 |
First trial, I made a mistake to set the origin at the middle top surface of the material which I should have set as the bottom left. So the machine started to mill the wax from the shifted location.

Result 1 : Failed
 |
|
 |
 |
I think there were lots of air bubbled trapped inside of the molds and made a huge empty space which made this zombie-like bear.
