I made all 3 sizes in all 3 fruits. 100 ppi, but the templates in my Etsy shop are 300 ppi, and 3.75 for all 3 templates.
As you can tell from the photo, I need to refill my ink cartridges! If your cartridges are fuller than mine, they will print out better. :) Click on the images for the full sized versions. Also, if you liked my watermelon box, take a look at my entry in the current Spoonflower contest. The theme was surrealistic fruit. I made a watery watermelon!
