Sharing some of the funniest failure we’ve managed to achieve so far 
Trying to get bubbles out of ballistic gel in an early prototype.
OK, let’s stick it in the oven at ~240 degrees F. That should work.
Yes that is a hard drive magnet + very large hemostat contraption holding the spine print in place. We all have to start somewhere. 
Drumroll…
Ohh…
The result was a little… Sci-Fi?
Moral of the story. Do not stick PLA plastic in an oven and what you think is going to be a heat sink actually does the opposite in a hot enclosed space.
