Description:
This is a prototype for an optical sensor that measures the width of plastic filament in real time as it goes into a 3D printer or a filament extruder. It is prototype #3 (other 2 are on Thingiverse as well ).The idea is that with a real-time width measurement the 3D printer could compensate the extruded flow for changes
