Saw a post online about using a pineapple as a pumpkin substitute for jack-o-lanterns. I happened to have some orange to yellow color changing filament. So a I took an already created pineapple model and made it into a jack-o-lantern.
Pineapple leafs are pointy and break easily.

The inside of the pineapple can be printed without supports but the mouth still needs support. Use support blockers and enforcers.
Bottom opening is a 26mm diameter. Blank so you can create your own version. Printing at around 150% is enough for me to use led tealights.
