This is a simple sink faucet extender to help people reach the faucet. The screw fits tight but should work with most printer's standard tolerances. This is great for anyone with a toddler or perhaps someone in a wheelchair. I would recommend printing in PETG as PLA might warp depending on how hot your water gets. Click the OnShape document link if you want to download in a different format or tweak any of the dimensions/properties of the model.  Happy printing!
