A remix of Jack1961's Filament Guide and Runout Sensor Bracket: https://www.thingiverse.com/thing:3450311 This bracket fits an Ender 3 (standard, Pro or V2) and attaches using the existing screws on the Extruder assembly that connect it to the Z-Axis Rod T8 nut. The original bracket did not fit the Filament Runout Sensor I got from Biqu with my BTT SKR Mini E3 v2.0; this Sensor is also sold on AliExpress here: https://www.aliexpress.com/item/32967243103.html The Runout Sensor I got is bigger than the one the original bracket was designed for & so this remix includes the following changes to fit the sensor: - Widen the upper portion of the bracket, the section that holds the Filament Runout Sensor itself - Move & expand the size of the hole that aligns with the filament outlet on the sensor - Increase the height of the bracket to match the mounting holes on the sensor - Remove the bracket's back lip as the filament inlet & plug interface are both on the back of the sensor In addition, I made some optimizations after iterating on a few versions: - Reduced the height on one side so that the filament runout indicator light is visible (the bracket is still snug enough to hold the sensor) - Created recesses for the screws & washers that connect the bracket to the Extruder assembly - Widened the base & adjusted the position of the parts that hold the sensor to ensure the filament outlet aligns perfectly with the Extruder inlet Quick & easy to print, no supports needed; my settings were: - 0.28mm resolution - 10% infill - 80mm/s print speed (40mm/s for walls, top & bottom)
