Probably the question sounds a little strange; however, I am looking for a filament which is breakable and not so steady and reliable as PLA. I want to print parts similar to the following gears for instance (They are from Lego, a children's toy).

They should break after some time or in any way become unusable after an accidental period (1 minute to several days) of use. Yes, you read right: I want to print parts that are frangible and probably will break! I plan to use Ultimaker 3 as 3D printer. So I'm looking for a suitable filament. Maybe I can merge two types of filament?

Could Ultimaker's TPU filament (https://ultimaker.com/en/products/materials/tpu-95a) be useful for my purpose? Or can anybody recommend me another filament that can be useful for my intended use? The primary purpose is that the printed part is not stable enough to serve its original purpose for longer than a foreseeable time (1 minute to several days). I appreciate your advice and ideas.

Note: I don't want to sell them; I want to use them for my private project. So please no legal issues. They are not helpful for my question. I don't ask for legal advice.
