Flightless Fruit Fly Feeder/Deli Cup Lid

These lids are designed for fruit fly culture cups, providing secure containment, airflow and a clean, controlled way to dispense flies. Each lid features a built‑in funnel and removable cap - open the cap, tap the cup, and the flies flow neatly through the chute without escapes or blockages. Close the cap again and the culture remains fully contained. The vented top maintains healthy air exchange for Drosophila cultures while preventing condensation and keeping flies inside. The funnel system makes feeding dart frogs or transferring flies between cultures far easier and more consistent than using open cups or mesh lids.   Model Variants (UK Retailers) This set includes three versions, each sized to fit common UK culture cups: 32oz cups from Fantastic Frogs (UK) 1000ml cups from Advanced Husbandry (UK) 520ml cups from Advanced Husbandry (UK) All three lids share the same functional design, with dimensions tuned to match the rim profile of each cup type. They print cleanly, require no supports, and are easy to wash and reuse. These lids are ideal for dart‑frog keepers, breeders, and anyone running multiple cultures who wants better ventilation, cleaner feeding routines, and a reliable way to dispense flies without mess or escapees.   Can be printed in both PETG and PLA however, PETG is recommended for longevity (PLA becomes brittle over time).
