Hi, well it is my first Instructables and very straight forward.

Step 1: Find Your Foam

I would recommend finding/up-cycling foam.
Usually where I found my foam is in packaging boxes, if you are lucky you could find a big one at the dumpster.

preferably the thickness of an inch would be good,
if any lesser the leads of the LED / resistor would come out from the bottom.(its not really a problem, it is more of an aesthetic decision)

the picture I have is one I organize for my common use parts, I can easily have a glance to see if I am short on any parts.

And that is the end of it!
