Punch tool and stencil pack

The Invention Engine stencil is a guide used to mark your cardboard. The stencil is organised into numbers that correspond with Invention Engine bit shapes and letters that correspond with rivet guides. The stencil also has a cardboard thickness gauge to ensure that the chosen cardboard is suitable to use with Invention Engine.

The Invention Engine punch tool is used for making holes in cardboard. Use the punch tool with the stencil to attach the Invention Engine bits and the hub to cardboard.
The punch tool can be separated into two parts, the inner and outer punch tool.

The outer punch tool is used to punch out the grid holes to create holes for the rivets. The inner punch tool is used to poke holes through the cardboard to create a perforated shape that can be pushed out by hand and ready for the Invention Engine bit to be secured.
