Nozzle pin for E6000 adhesive precision tips. Use this to clear out the adhesive from the tip/nozzle after using the adhesive.
Physical (printed) measurements:
Allow it to cool before removing it from the print surface. Don't leave it in the glue nozzle; it will become permanently stuck.
I've used the tool to clear out two nozzles so far, and it seems to work well, but I haven't used it long-term yet. I printed mine from Elegoo PLA Plus.
