Filament FAULT Detector

The device causes a 3D printer to "Pause" when filament goes missing or becomes tangled on the spool. After correcting the problem, a user can "Resume" the printing to complete the job. The Micro Switch connects to Octoprint on a Raspberry Pi.

Do your prints fail because filament gets tangled or because filament runs out? This octoprint-based system maybe the solution for your problem. This blog post has complete information about how it works and what it does:

Here's a link to the instructable and videos on how to assemble and setup:
............. https://www.instructables.com/id/3D-Printer-Filament-FAULT-Detector-Octoprint/
The STL files have been updated with an improved design, but the assembly instructions are still correct although the parts look a little different.

The design was created on Tinkercad and has been made public. You can remix on Tinkercad here:

This design works well with all filament sizes!

Thank you! Helpful to keep 3D designs open as it should.
