Bioengineered fly trap

Bioengineered flytrap inspired by the carnivorous fly eating pitcher plant. The plant uses its downward pointing hairs to create a smooth slide on which insects slip to their death, but find it difficult to get out. I designed this CAD model with hairs that can be 3D printed. These 3D printed hairs function to keep the fly in the trap in the same way as the pitcher plant.

The parts are designed to be used with a lot of different cup sizes. Apple cider vinegar and a little dish soap works great to attract the flies. This model has two parts for easier printing. These two parts are glued together. I used the spiralize feature in ultimaker cura for the cone base. You do need an FDM printer to make the hairs. I used the Creality Ender 3. No supports are needed on either part. Rafts are recommended for adhesion.

Please let me know how it works for you!
