Water faucet installer

I created this tool to install my drinking water faucet for my reverse osmosis water system. I have an 11" deep sink and it is VERY close to the wall so I could not get my hand up to tighten the lock ring on bottom of the faucet. It is an iSpring system, same as most of the generic amazon RO systems you can find. This tool will allow for the tightening of the lock ring on the bottom of the drinking water faucet when it is in a hard to reach area. The tool is hollow so the faucet stem can slide right through the middle of it. it has a 22mm hex bottom for a wrench, although you should not be cranking on this that hard. I added knurling for better grip with your hand. I really hope this will help people to install because it sure helped me! Please message me if you would like it modified in any way for your application. I could also make a shorter version. Center hole is 12mm in diameter. Total height of tool is 230mm. Approximately 160g of filament.
