Descrição
This is a prototype for a sensor that is intended to measure the width of plastic filament in real time as it goes into a 3d printing extruder. It is a proof of concept. The idea is that with a real-time width measurement the 3D printer could compensate the extruded flow for changes in filament width.
Prototype #2 is in progress, see http://www.thingiverse.com/thing:89044
