3D-printed multi-armed rotator mechanism for simultaneously testing a variety of lure blends

Abstract

With improvements in 3D-printing technology, the ability to convert the idea of an object quickly into an actual 3D object is becoming both more practicable and affordable. We have been developing a 3D-printed gear housing and a detachable sleeve mechanism with a variable number of rotating arms, to facilitate the testing of a variety of fruit y lures while controlling for environmental bias. The speed of the rotator mechanism is controlled using an adjustable DC step-down module and a series of 3D printed gears. Our current prototype runs on four AA batteries delivering 6V. For testing over longer timeframes or in remote areas, just about any power supply outputting between 5 and 40 volts can be attached. The model is small and has optional printed components that make the unit rain proof so it can be used for both laboratory and eld trials. The model can be printed on any 3D printer with a large enough stage. This model can be used to test lure blends for a variety of insects such as ies or beetles, in a variety of settings such as laboratories, pastures, orchards and forests.
