Printed on Prusa Mini.

Custom inserts organize AA / AAA / 9V batteries in 6 Qt. / 5.7 L Sterilite bins (model 1751).

Has cylinders on the bottom to slot into the sides of the bin. However the bins aren't perfectly parallel so it fits better the close to the middle and does not sit flush with the short handle ends.

I don't know the exact count of how many batteries fit. Hand a handful from a previous bulk purchase and a whole new pack.

The aa_aa model is meant to have 2 sections of AA. The aaa_9v has half AAA and half 9V like in the pictures.

Better to leave the height short otherwise its too deep and hard to get batteries from the bottom.
