Faucet nuts to hold a bathroom faucet. this is for a US faucet so it may not work in your country. I apologize, but I'm not very familiar with metric plumbing fittings. I did include a file with 2 and a file with just one. My advice is to print a pair and replace both. You're already under the sink. Get it over with. I've also added single files for a winged version, and a shorter winged version. Some people may struggle to tighten it all the way without the wings. https://www.thingiverse.com/jeff4smith has an excellent remix at https://www.thingiverse.com/thing:3615423 that inspired the wings. his version is shorter with wings that look great!

.2 is fine. 1.5 is definitely better

20% will work, 60% cubic will make it a lot tougher.

The nuts on the kids bathroom sink failed and I needed some new ones. The people at Home Depot and Lowes didn't seem to know what I was looking for so I designed some new ones in Fusion 360. These are much more heavy duty than what was originally there, and have held up well. I had planned on a fiber reinforced print but they seem to be holding up well!
