Blowing up Fingers! Take 2

After all the simulations and drawings it was time to print and test. This is the design which we have previously tested in CATIA. The bending motion is even better than expected, thus the model can be considered a success. Nonetheless we discovered that the material is very weak and the finger already broke apart. The next model will be reinforced at, what we discovered to be, critical points.
