Cap for Permatex Replacement Nozzle (40mm L with 3mm D + STEP)

I was really after a cap for a tube of Permatex Dielectric Tune Up Grease. Every single tube I open, the cap splits in half across its diameter. This is the third tube in a row where it has split. I'm starting to think its a chemical reaction between the cap and grease. Either way here is just a quick nozzle I made based on others work. Easily possible because of shared step files which should be a standard requirement for any model upload, seeing as they can be imported into mostly any slicer. Enjoy. More sizes in the future most likely. I have a feeling this is going to make a cold tube really difficult to squeeze.
