Ender 5 filament guide and runout sensor for Micro Swiss DD kit

thingiverse

This is a filament guide with a built-in runout sensor. It holds the end of the bowden tube running from your direct-drive hot end and stops the print if you run out of filament (assuming you have this enabled in the firmware). There are tiny circular paths on the side for zip ties to hold the wires for the hot end. The top hole is large and is designed for the press-fit, plastic bowden tube clip that comes with the [Micro Swiss Direct Drive upgrade](https://store.micro-swiss.com/products/micro-swiss-direct-drive-extruder-for-creality-ender-5), but will probably work fine with many other clips. The circuit board inside is pulled from a [Sunhokey Filament Runout Sensor](https://www.amazon.com/gp/product/B07N2GQHQT) (see picture). The top and bottom of the sensor are just pressed together, you can easily separate them without damage with a screwdriver and pull the sensor board out. It's a tight fit in the new enclosure, but I didn't want it to move around on me! I didn't create a top for this part because I wanted to be able to easily see the filament in the sensor module in case something gets hung up while feeding. So far, this works much better than the stock runout sensor which is hard to feed the filament through because it catches on the inside. Let me know if you're interested in the filament spool holder in the picture that estimates your remaining filament :)
