Originally modeled in Cinema 4D R11.5. Modeled and textured to replicate an actual flask, Frankenstein's monster image can be removed or replaced, but is included to use.
The lid is separate, so its rotation can be animated. In the c4d file, it is also grouped with the flap, which is also separate, so that when the group is rotated in Z around the hinge, it will open nicely. If this isn't the case, as with the obj file, the lid and flap will just have to be grouped and rotated in Z at the hinge to get the same effect.
