ender 3 filament shaft to suit spool roller.

thingiverse

this is a shaft i put together to suit the spool roller created by stauffen. i really liked the roller design but it didnt fit on my stock ender shaft so i made it to fit in the roller with about 1-2mm clearance for a nice smooth movementr. There is nuts for either end im am just testing them now and will upload shortly. i will remix his washer to suit as well for those who want one on the post end of the shaft, it is not required though it does look better. when i printed this i printed it upright with the block down low. the face the supports are on is hidden inside the metal post that way new nut has been added now testing the washer to make sure it will fit properly washer added, every thing fits with around 1mm tolerance. the washer on the shaft is a tight fit and needs a little wiggle to get it started but will slide all the way on.
