Making Valentines with Bellows Free Academy Posted on February 7, 2017February 7, 2017 by UVM FabLab Hello to Mrs. Brown’s class! Here are the three designs to choose from and create your custom laser cut Valentine: #1 3D Heart: This 3D heart is constructed from two individual heart cutouts. #2 Fox and Bunny: This fox and bunny design is engraved using a raster setting on the laser cutter and engraver in the FabLab. It’s like a combination of carving and burning into the wood. #3 Vector Heart: The lace-like cut out parts of this heard use the vector setting on the laser cutter engraver. Fill out my Wufoo form!
