High-­school science teachers can radically reduce the cost of building up science labs while giving students opportunities to engage in genuine design processes by introducing them to open­-source hardware. A vast collection of free and pre­-designed low-­cost scientific tools are available, many of which can be printed on a open­-source 3­D printer, including the printer itself. Not only can students benefit from access to research grade equipment, there are ample opportunities for students to build on, improve, and customize scientific tools as part of their curriculum. In this way the number and value of the open­-source hardware designs can expand with student effort, enabling a powerful motivating factor for science education.

Calipers are never an improvised adjustable wrench!!!
This is a good explanation of how to use calipers. I would also add that calipers will only provide accurate measurements if they have been…
After adding the external battery do you find the extra bulk gets in the way of some readings?
