Levers for faucet with rounded knobs

thingiverse

One of our faucets boasts a design with knobs that require wrapping one's fist all around them to grasp properly. This setup has an unhygienic flaw: germs accumulate on the knob when turning it on and are then transferred back onto your hands when you turn it off. Unfortunately, these rounded knobs make it difficult to shut off the water by elbow or sleeve due to their shape. Levers prove to be a superior option since they allow for more sanitary handling. Specifically, levers enable you to turn the faucet on by pushing one side and then off by pushing the other cleaner side. Alternatively, you can also easily turn it off with your elbow or through a sleeve. However, we don't currently have the time to replace the faucet, so I opted to print these slip-on levers that can be regularly sanitized in the dishwasher (I created two pairs). Although they are unlikely to fit your faucet perfectly, you may still be able to modify them to suit your needs or perhaps find inspiration from this design.
