Summary
Yes, gift cards are not very personal, but help them be more personal by giving them in a box you printed yourself!
Sketchup file included if you want to your own version.
Instructions
Print one of the two boxes, lid, the wrapper and the bow. I used hot melt glue to put it all together.
I printed the box with a Replicator 2 using Makerware. 100% infill, 2 shells, 0.20mm layer height with ABS.
