Real Kickstarters: the Filament Roller, an All-in-one Spool Holder with IR Sensor & Alarm

Now on Kickstarter, the Filament Roller is able detect filament stoppages, automatically pause prints when a filament stoppage occurs and alert you with a switchable 100 dB buzzer.
The Filament Roller can detect filament stoppages such as: jammed extruder, griding extruder gear, clogged nozzle, stalling extruder motor, and empty filament spool. The Filament Roller can automatically pause your 3D printer when a filament stoppage occurs.
It can be used as an end-stop filament runout sensor with Marlin 1.1.x firmware and a RepRap board. The Filament Roller can also be used as a filament sensor for OctoPrint or OctoPi with a Raspberry Pi board. As shown above it can be printed and assembled as a DIY kit. Printer files are freely available on Thingiverse.com so customers can modify the mechanical designs to suit their own needs.
Developed by independent inventor Chris Robertson, the Filament Roller is the first all-in-one IR filament sensor that can detect any filament stoppage and pause your printer using a simple switch signal. Designed to be used as a drop-in replacement for a filament runout sensor, the Filament Roller will allow makers to run any type of filament, any length of print, and no longer have to concern themselves with failed prints.
Tested through 2 prototype cycles, the Filament Roller is compatible with popular printing tools Marlin firmware (1.1.x and later), RepRap, OctoPrint, and Raspberry Pi. By using an infrared sensor, the Filament Roller never wears out, boasts the highest resolution on the market, never skips a step, and doesn’t drag on your extruder.
