First in - First out Battery Dispenser System

The Battery Dispensing System allows large quantities of AA, AAA & 9 Volt batteries to be stored and dispensed in a first in, first out order.

All parts are printed in 0.2 mm layer height without supports. 

I print with 4 perimeters for added strength. The extra perimeters will also allow screw holes to be enlarged slightly if required. 

Alignment pegs are provided to precisely align the dispenser halves and battery ramps. If a brim is used for printing the alignment pegs some sanding may be required to allow the pegs to be inserted in the guide holes. The fit should provide light interference for true alignment but not so tight that excess pressure is required to mate the 2 halves of the dispenser. The identifying labels may also require fine sanding on the edges. When gluing the halves together, I suggest that the thin sections of the ramps not be a glued surface to avoid uneven surfaces due to glue squeeze out. I normally only glue the outer perimeter and the area around the alignment pegs. Once the halves are glued and clamped it is a good idea to send several used batteries through the system multiple times to clean the surfaces of excess glue squeeze out. I clean the battery with paper towel between trips. Once you are satisfied with the tests make sure that all the batteries are removed and let the glue set completely before loading the dispenser with new batteries.

When this was originally designed about 5 years ago, I provided a set to a friend and I produced a humorous operating manual. I have included the same document in the files. I hope you enjoy.
