This product is a STL file of a 3d printable stencil with basic shapes and not a physical stencil. 3d printing is a great way to use technology in your classroom and is very exciting for kids. If you do not have a 3d printer available in your classroom or school, many local public libraries have 3d printers available that should be able to print the shapestencil.stl for you (most at low or no cost). Also many parents now are beginning to have 3d printers in their homes that would be happy to print this model for you. In addition, there are 3d printing sites available online that will print this model for an additional fee and shipping cost back to you. The file has been specifically designed to be a very easy print and is fun for kids to watch as the printer makes a physical object.
The zip file holds a 3d printable file for a stencil with basic shapes (square, rectangle, rhombus, circle, triangle, heart, and 6 sided star). A 3d printer that supports STL files is necessary to 3d print the STL file after it has been unzipped. You will also need to use your own 3d printer slicing software to convert the STL file into gcode that will be used by your particular brand of 3d printer. To use this file:
1) unzip shapestencil.stl.zip
2) upload "shapestencil.stl" to your 3d printer slicer software and convert to gcode for the 3d printer. I recommend you print the stencil at a 0.20 mm layer height and use appropriate temperature for type of filament (PLA recommended). No supports or brim should be necessary for this print.
3) Follow your 3d printer's normal printer procedures to print stencil.
4). Have students use stencil with paper and pencil to trace shapes. Consider challenging them to use several basic shapes (or even parts of shapes) to construct a picture (ice cream cone, seesaw, etc.)
5) Happy printing.
