Infinite power for an AA battery devices

Easy to make 3d print dual AA battery dummy with a build-in buck converter.
This battery dummy can power any devices that use an AA battery from any power source. It accepts input ranges from 4.5v to 23v. You can also use a power bank or USB charger as an input power supply.
In the video, I show you the dual cell version used with a mini LED video light. The single cell version is also available to download.
The original battery dummy is designed by Inversion on Thingiverse: www.thingiverse.com/thing:312059
