Filament alarm/sensor

3D model description

This started out as a quick'n'dirty hack for my printer but I've found it really useful so far.
It's a printed base with a battery, buzzer, switch and some PTFE tubing.

Your filament will run in the short PTFE tube and along the way holding the switch open, disconnecting the buzzer circuit.
As soon as your filament runs out/passes through completely, the circuit will close and the buzzer will start singing the song of it's people.

This instantly lets you know it's time to hook up a new spool!

I know you could do a more advanced version and hook it up to your controller but this is a simple add-on that works on any printer without any hacking, just put it between your spool and extruder and you're good to go!

Hardware needed:
9V battery
Micro-switch
Some wire
PTFE tubing
2x M3 screws for the switch

3D printing nerd and wannabe-engineer. Making random projects from RC trucks to nerf guns, interested in pretty much anything technology related.

Top projects are my RC vehicles:
3D printed half-track truck
-Fully articulated and driven treaded vehicle.
3D printed RC truck V3
-4x4 truck with full drivetrain model.
3D printed RC buggy V2
-RWD race buggy
3D Printed RC truck V4
-6x6 standalone truck chassis to build upon.

Been 3D printing since 2013, lately moving into mechanical design and metalworking.

I do youtube videos about most things I make.
