Bill of materials is 6 business cards, sticky notes, glue and a hobby knife (mine was very dull).
Finished product is a 3 slot Micro SD case.
After you mark the business card you will glue all the cards together, with the card you marked on top.
I did not have a sharp blade when I was creating this so my edges were not clean.
The purpose for this is you will glue around the marks so no glue residue is remaining in the card slots.
Glue around the marks and assemble middle section and back card together.
You will use sticky notes, what I did was use two notes for each section so I could press on the sticky part and once in place, I pealed the notes I touched so not to affect the glue.
Glue around the card and place the sticky notes, sticky side up.
Once all notes are in place peal off top notes.
Place Micro SD cards in slots and seal with top business card.
