Faucet lock - Squared handle

家里的猫喜欢玩水，最近学会了开水龙头。之前看到 https://makerworld.com/en/models/453240?from=search 制作的防猫水龙头锁，感觉很不错，无奈家里的水龙头把手是方片形的。所以自己重新做了一个，分享出来。 My cat knows how to turn on the faucet. To reduce my water bill, I designed my customized faucet lock, following the idea in https://makerworld.com/en/models/453240?from=search. This design is suitable for faucet with a squared handle.
