CR-10s Filament Sensor

thingiverse

I crafted this design to seamlessly pair with a PC4-M10 PTFE Push in Quick fitting, perfectly accommodating a boden tube. If you prefer using it as a standard spool dispenser for your filament spools, however, this specific fitting is not required. Please note that I am still actively refining this design. It's worth mentioning that the filament can sometimes become obstructed when attempting to feed it through, although I've found it manageable with minimal hassle. To facilitate effortless feeding, cut the end of your filament at a 45-degree angle. When installing this component, be aware that aligning the bolt holes can be quite challenging if both bolts are removed simultaneously. A suggested approach is to remove one bolt, then screw in a headless M3 bolt before removing the second bolt. This will allow you to easily mount the part to your printer by screwing in one bolt, then removing the headless bolt and securing the second bolt with an M3-12 bolt. I've included a picture demonstrating this setup, where a M3-20 was used for the headless bolt. The purpose of this bolt is to maintain alignment without requiring excessive threading. If needed, needle nose pliers can be employed or a long enough bolt can be used to thread it in by hand. Three M3-12 bolts are used to secure the top onto the base from below, although this part fits snugly and the bolts can often be left off if desired. I'm also including a picture of my spool dispensing system, inspired by Thomas Sanlanders' YouTube video. Separate files for this design will be uploaded in due course. Update 3-15-18: A revised file has been uploaded to improve part integrity.
