3D printers are becoming far more common as popularity has increased, prices drop and they become more usable. However, there is a learning curve and so a printer owner, user, parent, teacher, or student usually stall out of projects once they have printed some toys or a few household items. To get beyond this, most people need a "starter set" of objects as a beginning point in their explorations, partially just to see what is possible, to get more proficient, and to learn techniques that can be used for other projects and still have something worthwhile to show for it.3D Printed Science Projects fills this need with modules (projects) that combine a downloadable 3D printable object file (called an STL file) with instructions for how to use the object (for projects at home or in a classroom) and suggestions on how to create the file on some standard types of 3D printers.
