Filament Runout Sensor Case - REMIX

thingiverse

Carries the same simple design, however adjusted for better operation of the roller switch without case/switch modifications. 15oct2019 Updates: The following adjustments were made to support a RAMPS or similar board with 3v3 to 5v pin available at/near an endstop/runout pin. This allows for an LED to be lit when there is no filament in the sensor. 1) Added a third version with PTFE connectors at both ends 2) Adjusted threaded bosses from 5mm to 5.3mm in length for smaller profile CR-10/Ender 3 PTFE couplers 3) Created versions with hole for 3mm LED 4) Added Coordinate systems to cases so STL's will be flat w/o re-orientation in slicer 5) Added notches in all three covers for LED clearance 6) Adjusted slot for wire due to using a 3mm diameter, 2 conductor shielded security wire 7) Created additional instructions for wiring in a LED and a basic Klipper firmware config. There are 3 different cases and 3 covers to choose from: 1) Standard Case w/wo 3mm LED hole 2) single PTFE Adapter Case w/wo 3mm LED hole 3) double PTFE Adapter Case w/wo 3mm LED hole a) Right Arrow Cover b) Left Arrow Cover c) Blank Cover Print one case for your needs. Models are designed to feed from left to right when filament is at the top position. Mirror in your slicer if you need a right to left flow. Print one cover for your needs; right flow, left flow, or blank. The switch has 9mm between mount holes and can be purchased from Amazon: https://www.amazon.com/gp/product/B06XFL4MZ2 CR-10/Ender 3 Couplers: https://www.amazon.com/gp/product/B07T7P1WRB PC4-M6 Couplers: https://www.amazon.com/gp/product/B07TC3Q7R4 I can adjust the posts if your roller switch is not 9mm distance and 2mm diameter. I added arrows to the case for filament direction and thickened the cover adding an arrow and text.
