Introduction
Make your own battery holder with 3D printing and some Maker Tape. This can be a fun project if you've got a 3D printed in your classroom and some of our Maker Tape on hand.

Circuits need power, and if you need a battery pack, or a convenient holder for a single AA or AAA battery, you can make your own as long as you've got a 3D printer and some Maker Tape.
-
This project will provide files and demonstrate how to create your own battery pack, including how to create a conductive path for multiple batteries.
-

-
You can download the file and print it on your own 3D Printer.
-
Find it in our GitHub repository: https://github.com/BrownDogGadgets/3D-Pr...
-
You'll find ready-to-print STL files for one, two, and three AAA and AA batteries.

For the single battery holder you just need to add a piece of tape looped around each end so the positive and negative side of the battery will make contact with the tape when pressed in place.
-
For multiple batteries you'll need to connect the negative of one battery to the positive of the next battery. This connects the batteries in series.
-
-
-
Once you have your tape (or tape paths) in place you can add the batteries.
-
They should fit in snug so that the ends are touching the Maker Tape. (If they do not, you can just add another layer of tape.)

-
-
You can use these battery packs in a circuit the same way you would use any battery pack.
-
You can even use a tape loop to stick the battery pack right down to your Maker Tape pathways.

-
Maybe you'll come up with some new ways to use these battery packs.
-
Got some batteries that are down to just one volt? Put three of them in a holder together and you've got a 3 volt battery pack which is equal to a battery pack with two fresh batteries. A great way to get a bit more use out of old batteries.
-
Could you connect the packs in parallel? Sure! It's just a matter of running Maker Tape for a specific pathway.
-
One of our favorite uses is to pop one battery into a holder to check it with a multimeter. This solves the problem of trying to hold the battery and the meter probes at the same time.
