Remix of 3Deddy's filament runout sensor with teflon tube extsion

I remixed 3Deddy design so that you can use the three counter sunk m3 screws that come with the cr-10 s. I modified all three files to accept the new hex plug nut. I printed the plug nuts separately at .06 layer height. After you have all the parts printed place each plug nut into the base and use the m3 screws to "tap" the plug nuts from the hex side. the clearance that I used for the plug nuts is .08 mm. I have also included a .1 mm in case the .08 is too tight.
