Create an easy 3D valentine with this Heart Cube Shadow Box. It has the high impact of being 3D yet still folds flat for mailing. The assembled cube is 3.75” and it fits in a standard 6.5” personal envelope when folded. There is a printable assembly directions  insert to add with the card included in the download.

The download includes files in SVG, PDF, DXF, and PNG formats for use with either the Silhouette (DE required for SVG) or the Cricut Explore. Silhouette users without DE can use the dxf files. They are downloaded in a zip file and must be unzipped.  Complete print and video tutorials are available online here and are included in printable PDF format in the download. This project is an easy beginner's level 3D project. 

Download a free sample file here to be sure my files work on your cutting machine. 

PDF files can be cut by hand with patience! SVG files can be imported into other cutting machines like the Brother ScanNCut as well.
