Step 3: The mesh
First what you do is cut out the mesh roughly to the shape of the tin, then trim it to fit perfectly. (well, not perfectly)
Now you just put it in the Altoids tin.
Step 4: The stand
Cut them out( I used sheet metal scissors, but a hack saw would work.)
Using the scissors( or saw) cut a line half way to the top of the sheet metal on the two smaller pieces.
Cut two lines in the bigger piece, about thirds.
Trim the corners to fit the tin.
You are now good to go!
