About this 3D model

One of my pet peeves of 3D printed battery holders is that if the battery is out of spec, or even just gets put in a bit crooked, the whole thing clogs up. This solves that. How? It's a gravity-fed, simple path holder. Slightly too large batteries are pushed down by the others, and each one gets pulled out the bottom. They are nestled in the bottom curve ready to be pulled out whenever, but with the weight of the others, won't get jostled out by tilting or earthquakes.
