Linear Measurement Training Sticks

This is a OpenSCAD script for creating a bunch of sticks. Each stick is numbered and each stick is a different length. The lengths are incremented according to the user's input.

Laser cut or 3D print the sticks and pass them out to students. Students will measure the sticks and enter or record an answer. You can check their work based on the number of the stick which corresponds to a measurement. If the students figure out the relationship, they're probably beyond needing to learn how to use a ruler.
