Filament Runout Sensor Microswitch Enclosure and Guide

thingiverse

My requirements for the filament runout sensor enclosure: 1. The enclosure must be mounted directly to the printer, eliminating any loose or dangling connections. 2. Wires should exit the back of the enclosure to avoid interfering with the x-axis. 3. A guide is essential to prevent stress on the filament as it moves through the system. 4. Printing the enclosure must be straightforward and uncomplicated. Acquire affordable tiny switches from a reliable provider (I bought 10 for $8 from Amazon). This setup should seamlessly integrate into your existing printer configuration, particularly if you're using Octoprint. The Octoprint-Enclosure plugin simplifies the process by handling complex tasks on your behalf. Other plugins may be available but lack maintenance or functionality, such as issuing GCODE commands (e.g., M600 for filament change) when the sensor is triggered. This modification was a cost-effective and relatively simple addition to my Ender 3 Pro. However, it should be compatible with most Creality printers featuring the same extruder setup. The design has been adjusted by rghawi to meet all my requirements. The orientation and outlet for the filament were modified to ensure it hits the extruder without any bending or stress.
