An extension for a faucet to allow young kids to reach the water stream.

Print in your material of choice. PLA might eventually degrade, but hopefully not before your kid grows a little taller. Seal with polyurethane or acrylic if you like, and fasten to the faucet with a zip tie or rubber band. No 3D printed material is approved for use with potable water, so this is for washing hands.

Note that this design was made for a faucet that angles upward. It'll work on flatter faucets, but won't reach as far.
