Description

I've tried just about every AA or AAA battery dispenser I could print, and I never fully liked any of them. Many of the ones I printed either got clogged if you didn’t insert the batteries correctly, or they were just a mess overall. Even worse, some were almost perfect but didn’t work with rechargeable batteries, which I mostly use. Others didn’t support all battery types, like C, D, or 9 Volt.

So my goal was simple: make a battery dispenser that was easy to use, required minimal effort, and, as a bonus, was compatible with Gridfinity. I think I’ve achieved that.

The file includes all the options I needed, plus a few more. Here’s what you get:

AA + AA
AA + AAA
AAA + AAA
C
D
9 Volt
18650

The model is straightforward. You print the Gridfinity housing and an insert. It’s important to install the insert correctly; otherwise, the batteries won’t slide properly.

Rechargeable batteries slide the best, especially the Amazon Basics ones. They have a smooth bottom and are heavier, which helps. Light alkaline batteries also slide fine, though you may need to slide them a few times to break them in, if that makes sense. I designed this dispenser primarily for rechargeable batteries, since using a first-in, first-out system helps them wear evenly.

Important: Place the “round” batteries with the positive (+) side facing up and the negative (–) side facing down. The battery slides more smoothly this way, since the negative side is flat and even.

Printet very well in PLA. however it does not work for me. the batteries does not slide down but topples over instead.

I see the problem. Your batteries are not facing in the same direction; you have some with the positive side up and some with the negative side up. For this to work the best, you want the positive side up and the negative side of the battery facing down; the battery slides on the negative side as it's the flattest and smoothest part of the battery.

That was to show them both ways :) I found out that it depends on the batteries. Duracell slides fine but variata does not as it has plastic coating on the end.

Printed Perfectly! Thank you for sharing.

im giving this one a go - see how it works. Maybe need something to keep them vertical. For the 9v batteries, i do think a cover of some form would be needed - you do not want anything metal shorting those out - that would be a fire risk. Maybe just store them face down

I wouldn't store the 9 volts facing down, as it won't slide. If you're worried about the contacts touching, there are snap on lid covers for 9 volt batteries. https://makerworld.com/en/models/518031-9-volt-battery-cap?from=search#profileId-1618067

I printed some AA and AAA and ended up going in a different direction using standard gridfinity extended models that work well.

Very good support, however the toothpick batteries fall out and it is difficult to pick them up from the gap

Works great, doesn't properly allow batteries to slide forward unfortunately but still functional. The batteries just kind of fall forward instead of sliding forward.
