Thermal Paste Cap

This is a very simple replacement cap for those tiny thermal paste syringes you get when buying computer heatsinks, it's knurled for better grip.

I lost mine because I couldn't get grip with my hands, I used a pair of scissors for leverage, and then it shot off somewhere. I always carry the paste in my PC repair toolkit and without a cap I couldn't do that anymore.

I printed mine in PETG, but obviously it doesn't matter.
