WD40, Original Formula
WD-40 is one of those random workshop staples I keep around for stubborn parts and general maintenance moments. When you’re building and assembling, sometimes you just need things to move smoothly or stop squeaking. It’s not a “3D printing” tool, but it’s a super handy helper.
