This document is a guide to making a portable device which can be used to monitor the air, in terms of PM2.5.

These tiny particles can come from a variety of sources and could be harmful. This device will indicate when the relative number of particulates in the air is high.  It could be used to monitor the air in a workshop.

The file contains the STL files for 3D printing the base and armature of the electric motor.

Instructions on building this are in GL365.

This is a 'make-it' guide for constructing a DC motor from easily sourced components and 3D printed parts.

The 3D print files are available from GL365A listed below.
