I needed a tool for removing the aerator on my faucets because the water has a lot of hard minerals that build up in them. The PETG was durable enough for many cycles of removal and reinstall. PLA should work great too though.

I've modeled up 18.5mm and 24mm sizes, each on their own plates, so the print time is actually only around 30 minutes for 1 size. I hope others find this useful and can save a few bucks!
