Filament Run-Out Sensor Alarm

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2116492.

I reworked the original design in Tinkercad to fit a switch I bought from RadioShack. Here is the switch I used: http://shack.net/2lpcuDF

I connected it to a 6v buzzer and a 4.5v battery pack with on/off switch.
