I have designed an applicator tool for applying lubricant to z-axis lead screws. This applicator is built to wrap snugly around the screw, spreading lubricant evenly along its surface. The tapered hole helps prevent excess lubricant from spilling out, making cleanup easier and less messy.

I printed it in PLA and no supports needed.

And finally, amidst the sea of tools out there (seriously, it's like a tool jungle), I'll just say this: pick the one that vibes best with your maintenance mojo. Here's hoping this little gadget adds a sprinkle of ease to your tinkering adventures!
