Unbreakable Door stop

Helps stop the doors from hitting the walls(or mirror in my case) and no kid can brake it by stepping on it! This is the product of a trial and error when looking for the right material. The photo shows a test model printed on a PrintrBot kit. It is still holding after 1 year. I am waiting for it to break so I can replace it with the much better print from a CTC
Of course it could be taken to a different aesthetics level by somebody with more time...
