Bicycle Cantilever Brake Spring Washer

This is a model of the plastic spring washer that is sitting under the arm of the cantilever brake system on the 1995 Giant Acapulco mountain bike on my porch. They're apparently not available for purchase any more and may be an important part of the bike's braking system. (I'm not really sure; I'm just getting into biking.) However, mine are cracked and falling apart. Since it's just a small bit of plastic, why not try to model it and get someone to print it for me?

I've never 3D printed any
