Touch Up Paint Cover

I ended up using a few of these 1" Touch Up Painters (no affiliation) to paint the cut edges of wood siding.Adding a 3d printed cover from 95a TPU made all the difference in terms of being able to use the painter intermittently. Not sure why these don’t just come with a cover included so the paint doesn't dry out. (The little turn valve is completely useless and breaks almost immediately.)Feel free to customize model directly in onshape.
