Ever had a print fail because you leave the machine to make a beverage and the filament runs out?
We have, so we developed a simple mechanism to sound an alarm to warn you when the end of the filament reaches the end of your filament guide tube.
This version comes with a mounting bracket designed so the sensor fits between the filament spool and the end of the guide tube on a Replicator 2 or 2x. You dont have to use the bracket and could mount it with double sided tape, zip ties or the bolts running through the body on almost any machine.
Requires a 9V battery (not included). The power is only used when the alarm sounds, so if you use an alkaline battery (which have minimal self-discharging) it will not go flat for a long, long time - we estimate over 1 year.
