This is a tray to support your maker3 or maker cutting mat when you are cutting something out. Previously we had supported the mat by hand, but as our designs get more complicated, it has become a tedious task. This tray was designed to fix that problem. We found it especially useful when cutting intricate paper designs as those would lift and tear when bent. Package Included: 1xCutting Mat Extender Support Set For Maker3 or Maker Series NOTE:This Tray Not Compatible With Cricut Maker3 And Maker Machine , All the machines in the pictures are not included
