Holds up to 12 AA batteries in a compact tabletop hopper. The batteries go in the top and are directed to the bottom of the hopper by 3 ramps.

I want to make the next version automatically charge the two batteries at the bottom of the ramp and would love input and thoughts on this idea.


The entire thing can be printed without support.

Note that BatteryHopper.skp has both sides defined as components. In order to print the model you'll need to "explode" them so they're attached to the ramp base. For some reason I couldn't get it to print it correctly without doing this.

any chance you have one for triple a batteries?

Some people have done this by scaling the design in the slicer. Here's an example: http://www.thingiverse.com/make:82422

Thought about using customizer to make the height variable? (so you can store more than 12?)

I haven't. I'll have to give that a try.

It would be simple to add contacts to the bottom to charge the bottom batteries. Just drill holes there where the ends of the batteries are. Make some contacts which will just brush the ends of the batteries as they roll into position. I'd use thin wire bristles from a wire brush. use wires to connect those brushes to the terminals in a battery charger. Plug in charger, and you're in business! Then you can just drop dead batteries in the top and get fresh batteries out the bottom.

That's what I was thinking. I'd also want to make sure the charger could go in either polarity, so I wouldn't have to be careful which way I put the battery into the hopper.

you could try to make a Arduino program that uses a voltage sensor to show the voltage of the battery and if the voltage reads negative then the battery would have its - port agents the + side of the sensor telling the Arduino to open the - charging relay on that side and the + one on the other. It would have to have a total of 4 relays and 2 on each side.
The only problem with this is that it would require the battery to have a bit of voltage in it

I don't think there is a way to make it where you could put batteries in either way. I don't know of a charging circuit for NIMH batteries which works like that. Besides, how hard would it be to just point all the batteries one direction? You do that when installing them in devices, so you can do it when putting the dead ones back in the holder/charger thingy. I'm printing one of these holders right now. I'm going to try this charging mod myself when it's done in a few hours. I'll try and post pics after I get it working in a day or 2.

You could also make a slot for the batteries witch only takes the battery if it's orientated correctly.

What are your suggestions for infill? I want to print but i also don't want to use tons of plastic on the base?

Thanks love the design :3


I think I used about 25%. You can probably get away with less if you use more top layers.

Print height and width at 0.88, depth at 0.70 for 12 x AAA

Comments deleted.

Any chance you could add the AAA, D, C and so on to the collection?

That would be great.

I currently do not have plans to build a model for AAA, D and C. The SketchUp source file is included for download, so anyone should be able to modify it. Someone already made one for AAA batteries by simply resizing the model: http://www.thingiverse.com/make:77137http://www.thingiverse.com/mak...

I did a scaled-down version for AAA a couple of days ago. Worked perfectly.

do you have the scale that you used for AAA, that would be greatly appreciated thanks

You can click on the picture of my make - it's spec'd in my Description section, here: https://www.thingiverse.com/make:82422 .

But just in case the links aren't working:

For X (the front of the battery holder is on the x-axis) scale = .89.
For both Y and Z: scale = .73.

I saw your posted make, it looks great!
