Preheat oven to 350°F (175°C).
In a large bowl, mix together the almond flour, tapioca flour, coconut flour, and salt.
Add the olive oil and 2 tablespoons of water, and mix until a dough forms. Add more water as needed, 1 tablespoon at a time, until the dough comes together.
Roll the dough out between two sheets of parchment paper to about ⅛ inch thickness.
Cut the dough into desired shapes using a knife or cookie cutter.
Transfer the crackers to a baking sheet lined with parchment paper.
Bake for 12-15 minutes, or until the crackers are golden brown and crispy.
Allow the crackers to cool completely before serving.
