Modify a Mint Tin to Hold Business Cards

All you need for this modification are business cards, mint tins, a fine half round file and tin snips.

This shot shows that the rounded and rolled corners of the tin make the fit going in and out too tight.

First, file the front two corners down through the rolled edge.

This is what the corner looks like after filing it down.

You could do all of this with the file, but that would be too tedious.  Use the tin snips to cut down the sharp tail left by filing.  Finish it out by filing all the edges smooth.  Repeat for the other corner of the tin.

This is what the tin looks like with the front corners look like at this stage.  Loading the cards is easy enough now.  I suppose you could stop here and use it to carry your cards, but getting one out easily will be a challenge.  In the next few steps we'll add a mod to make it easier to pick up a card.

I marked the center, and lines to layout all of the areas I wanted to cut out.  You don't have to.  You can just wing it.

Cut out an opening.  I think it's easier to do it in stages.  The tin distorts less.  Be sure to leave the catches for the lid.

Finish the opening by filing and getting rid of the sharp edges.

Done.  Load your cards, and take the tin with you to promote yourself.
