Since it had been a while since I touched 3D softwares – I followed a tutorial and even copied a silicone model. After some practice, I created my own! I don’t have solidworks on my laptop so I used blender to make it!
Based on the sketches I had last class, for the first mold, I wanted to do something more simple to ensure that this bubble like actuation will occur which is the first sketch with circles. Afterwards, I want to test more complex molds that will allow more organic texture which feels/looks like a brain. I realized that my previous iterations to these were incorrect because I inverted the mold.
This was the template/model that I copied 
This is my own model
