This is a cap I modeled for the Vype Epen3 by Lucky Strike. I found that the capsules were sold without any cap, and that isn't hygienic.
So I modeled this that fits on the capsules. I suggest you printing it with TPU, because with its elasticity it will not fall of the e-cigarette.
It's a simple model that works perfectly!

Let me know if you like it, if you print one yourself (maybe upload a photo, I'll really appreciate it!), and also consider checking the other stuff I make on my profile. I'm still learning how to model things, but I have lots of ideas and I'll upload them soon!

If you also want to make a tip to me, I will really appreciate it, and
I'll think about continue making this stuffs 'cause I will know that
someone likes my design!
