Having a place for everything is key to a productive workbench.
We want to make stuff, not look for stuff! :-)

While we could make the cabinet out of wood, as long as your the parts are not too heavy, foam core is strong enough, inexpensive, and quicker to make than a wooden cabinet. Plus, no one has ever gotten splinters from foam core! :-)

I was able to make a 30 drawer parts bin for $4 by shopping at my local Dollar store.

Parts List:

3 X "Sure Fresh Mini Storage Containers with Lids, 10-ct. Packs"
That's 30 containers with lid for only $3. Amazing...
1 X Foam Core Board, also $1
Recycled cardboard for the back

Tools List:

Box cutter
Ruler (metal recommended)
Hot glue gun (not pictured)

Step 1: Plan and Cut

I worry that the boxes would easily fall out, so I slanted the shelves slightly (each shelf front is slanted 1cm higher than the back).

I also made the shelves not as deep as the actual container so I could grab the bin either by the sides or by the top and bottom.

Remember to take account the thickness of the shelf when measuring the height between shelves.

I arranged my containers 5 across and 6 high, but of course you can arrange them anyway you wish.

Step 2: Hot Glue

Hot glue dries quickly, so I hot glued one side first, and then hot glued three of the shelves on the other side. The remainder of the shelves ,I hot glued the remaining shelves afterwards and used a screwdriver to cleanup the excess glue.

Step 3: Done!

For the backing, I recycled cardboard packaging. Alternatively, you can use foam core for extra strength.

If you have tips, on how to hot glue a lot of surfaces at once, please leave a comment. That's one part that I'm not pleased with. Keep making!
