Bottle Cap Trap for Flies & Pests

I designed this cap to upcycle plastic bottles into effective insect traps, perfect for protecting your fruit trees and olive groves. Key Features: Universal Compatibility: Designed to fit the threading of standard carbonated drink bottles (soda bottles), which are typically stronger. Color Attraction: I highly recommend printing this in yellow filament, as the color is naturally attractive to many harmful insects. Weather Protection: Just like the most popular commercial traps, it features a top cover (rain shield) to prevent rainwater from diluting the bait, making it last much longer. Easy Mounting: The cap includes a built-in loop at the top for a string, making it easy to hang from branches. Eco-Friendly: Fight harmful pests effectively without the use of pesticides. Print Settings & Material: Material: I highly recommend using PETG. Since the trap will be exposed to direct sunlight and outdoor conditions, PETG offers much better UV resistance and weather durability than PLA, ensu
