Introduction: Crackling Small Tool Organizer

Every year on January the 1., the streets where I live are filled with burned batteries and trash from fireworks used to celebrate New Year's Eve.

This year I got one of the remaining used batteries layed aside in the garage and it was there until I recently got an idea for a new life for the trash: A small, but handy tool organizer

In this project I will primarely used material that have been used before for other purpose, left over material I already have in my workshop and of course some glue, paint, prints and so on which are difficult/impossible to reuse

Step 1: Materials and Tools


  • 1 Used fireworks battery
  • Some skinny 3mm MDF that earlier was used to protect some new furniture we bought
  • A piece of 8mm threaded rod
  • A handle that originally came from a car workshop where it was sitting on a carriage holding the hose for exhaust gas


  • Handsaw
  • Pencil
  • Try set square
  • Clamps
  • Laminator

Helping materials

  • Black paint
  • Wood Glue
  • Sanding paper
  • MDF filler (or similar)
  • Black permanent marker
  • Black tape
  • Laminating pouches

Step 2: Remove What You Don´t Need

Remove all you dont need:

  • Sorrounding carboard
  • Red silk paper
  • Black gun powder
  • Ect

I ran over the battery with my shop vac, and before I proceeded to the next step, I level the top with a piece of MDF and a mallet

Step 3: Cut Sides and Bottom

My firework battery is ca. 15 cm on each side, so I cut the MDF to that size.

As you can se from the picture the box is not 100% square but since it does not affect the final function of my project I leave it as it is. I also cut a bottom plate and make a test fit with two rubberbands.

Please remember to add the thicknes of your board to two of the sides so everything will look nice when finished. I did not, but you will have no pictures of that here :-)

Before moving on to step 4 I painted the top of the tubes black with some spraypaint

Step 4: Glue It Together and Make It Smooth

Now it is time to get sticky

  • I added wood glue to the sides and bottom and glued them to the cardboardtubes
  • As it dried I clamp it together as good as I could
  • After 24 hours I removed the clamps and sanded the corners with sanding paper
  • There where some small gaps in the box whom I filled with a MDF filler
  • After the filler was dried I gave it a light sanding again
  • Some of the black paint has crackled and to repair that I 'painted' the spots with a black permanent marker

Then the box was finished and smooth

Step 5: Decorate the Sides of Your Toolbox

This step is not 100% necessary, but it makes your tool organizer personal and more decorative

  • Find some pictures in a search on Google or by looking through your favorite pictures.
    • I found some pictures I liked and printed them in highest resolution for my printer.
  • To make it more resistant to dirt and greasy fingers, I decided to laminate the images
  • After laminating the the prints I cut the excess plastic off before I glued them to the box
  • To distribute the glue under the lamination I used a roller, but you can also use a scraper or a discontinued credit card
  • To make sure the pictures stays in their place in the future, I rolled the edges with canvas tape

But you may also leave your box as it is or maybe paint it in some vibriant colours

Step 6: Add a Handle So You Can Carry It Around

I'm close to the end of my project now. I only needed to mount the handle.

  • I measured the 8 mm rod and cut it to the correct length
  • Cleaned the handle with some wipes
  • Mounted the handle on the rod
  • Applied a thick layer of super glue to the rod and turn the rod into the center of the old battery Waited for some minutes for the super glue to dry

During a previous test I discovered that it looks like a piston box, so I place a 'Dynamite logo' on the box.

The box is now ready for the finally step .........

Step 7: Fill It Up With Tools

Now fill your organizer with tools.

Step 8: Extra Info - Bonusmaterial

I added some feet to the box. I made them from wine cork (actually is it plastic) cut in 4 pieces and and glued them to the bottom

I was also thinking of screwing two terminal post in the box as decoration to make it look like a real Dynamite Plunger Box

Instead of pictures on the side you could add some information - for example a resistor colour codechart, a tabel showing convertion between inch and mm, usefull Arduino codes and so on. If you need inspiration search for Cheat sheet

Finaly I was thinking of a way to make it possible to change pictures on the sides, That way it can suit your different needs in different situations.
