Free Cup Cap Lock Replacement

thingiverse

Bring your own cup to buy your coffee is the way to reduce paper cup waste to save the trees, but my free Cup is missing the locking cap, I don't want to buy a new one just lost a small piece of plastic and dump the cup to landfill so I create a replacement cap lock for it. I guess losing this cap lock would always happen on this product, so I share it with you guys.
