Crayon Maker/Recycler Kit with Sharpener (Parametric)

This is a fully parametric kit that will allow you to make triangular crayons (or recycle bits and pieces of old crayons into triangular crayons) and a sharpener. This shape is easier to cast, easy for little fingers to grasp, and easier to stack. It also won't roll off the drawing surface, and promotes a proper pencil grip.

Many aspects of the kit are parametric, such as number of crayons, thickness, length, sharpening angle, etc. You may need to tweak the settings a bit for the best results on your printer.

There's an STL for each part using the default settings. You can make just the crayon mold, or both the mold and a sharpener that fits the crayons you specified. Follow the instructions and take a look at the pictures for details.

This is a great project to do with kids -- I've tested it! :)

There are 21 parameters, and the code is fully commented, so tweaking it should be straightforward.
