👉   Play freely and build endless fun at home with STEMFIE, the free 3D-printable educational toy   👈 

This 3D-printable frame holds a standard 85x55 mm business card, which you can glue to any surface you want to label. It is purposely designed to mark empty filament cardboard boxes, which are perfect for storing your STEMFIE projects. 

Along with the business card holder, there is also a template you can easily use to cut labels measuring 85x55 mm.
