USB to D-Cell Battery Eliminator

thingiverse

I needed a battery eliminator for my minnow bucket bubbler pump. The red one in the photo is a finished prototype I first made one that required hard wiring but other people wanted one, so to reduce labor, I came up with this design. I merely glued the lid on because I added an access hole to adjust the voltage if needed. For best results use Tree supports. I got all the parts from Amazon and wiring is simple.
