minimalistic quick battery holder for 2/3/4/6/8/12 AA/AAA cells (e.g. attach to cabinet door; vase mode)

I intended this model to be mounted on the inner side of some cabinet doors (using double sided adhesive), which is most often some unused space, but easy to access. I also attached one on the inside of a drawer. Or attach 2 of them together back to back for some standalone holder. Or use them just as they are. The cells slide out easily, no fumbling required.

My previous version had quite some pointy edges, but for publishing the model I rounded the design and it's much nicer now (optically and haptically).

The holes on the bottom allow measuring the voltage without taking the cells out.

Printing: vase mode, 0.6mm extrusion width. 

I used PLA, 0.2 mm layer height and a 0.4mm nozzle.
