This openscad code and models solves the Challenge: "Back to the drawing board" Design a tool that can be used for drawing or sketching. With the following parameters: "Small" and "Teenager" and "Jeff Koons" and "loft". This small french curve and stencil drawing tool is inspired by Jeff Koons balloon dog sculpture. The balloon shapes are created using a loft. Stencils for making regular polygons of different sizes are often used by teenagers in art classes. I have uploaded several stencil designs with different inside shapes. For Example: The STL file named "stencil100-circles.stl" is 100mm across and features circles ranging in size from 15mm to 3mm. The STL file named "stencil100-multi.stl" is 100mm across and features different sized triangles, squares, pentagons and hexagons. You can use the openScad code I have uploaded to modify the size of the stencil and change the shapes inside this stencil. Customize by using the free openScad program and downloading the .scad file. openscad.org
