Cosplay wings mechanism

thingiverse

This is an experimental mechanism for creating cosplay wings with the aid of an electric motor. It has only one degree of freedom, allowing the wings to move up and down but not flap forward and backward. Since it employs a worm geared motor, it should be able to sustain the wings' position indefinitely without any energy expenditure. This mechanism could also be utilized for a giant mechanical claw or other devices that require the same motion. The type of motor used is a Valeo Type 5 11v heater flap actuator. I'm uncertain what model of car it originates from, but these motors should be readily available at affordable prices on eBay (I've noticed different shaped axles on these models; you may need to customize the main cog based on your selection). However, there are a couple of issues associated with using this motor: first, it employs an automotive connector that will require either a compatible cable or soldering to connect it. Secondly, the rotation is limited by a fixed number of degrees due to a piece of plastic protruding from the case that prevents the main axle from turning beyond that range; this is relatively easy to modify. The arms are constructed from 21.5MM plastic pipe, which should be readily available at most DIY stores. A few small bolts may also be necessary for assembling the parts. The .stl files have been designed to minimize overhangs for convenient printing. EDIT: a low-quality video of an early test run is accessible here: https://www.youtube.com/watch?v=SYZBNwmDCMI
