Credit Card (Present) Box

It's a little parametric box, that holds e.g. credit card sized vouchers. It is easy to print (no supports) and one can easily modify the contents of the lid. I made one with the logo of my brother-in-law's company.

The lid slides halfway to the top, then flips 180° to the back and can slide back down to hold securely. It can easily be popped off with a little force and swapped for, say a different color version. The size of the hollow can be set in the OpenSCAD file.
