Creality CR-10 Filament Runout Sensor

thingiverse

Upgraded filament runout switch for the Creality CR-10. We made the whole assembly out of aluminum, except the tube that the filament passes through is stainless steel and the clear cover was printed out of clear PLA. I printed off some prototypes of the assembly when I was testing fit though, and this whole assembly (with the exception of the stainless steel tube--for durability's sake) could be printed. If you do try it out, please post a picture! ***If any of you are interested in having any of the aluminum or stainless steel components made, send me a direct message.*** Miniature Snap-Acting Switch: https://www.mcmaster.com/7779k42 Pneumatic Bowden Tube Fitting: https://www.amazon.com/gp/product/B073TTWWN1/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 Notes: -See pictures for how the stock Creality filament sensor switch was modified and wired to the Snap-Acting Switch. It worked best for two of the leads to be soldered directly to the plug on the switch which put the board at a bit of an angle. The cover is designed to allow for this angle. ***IMPORTANT*** Do NOT tighten down the screws all the way when attaching the sensor to the printer. Tighten them up until the point that the screw heads make contact with the lock washer.
