Intermediate Ring, for Cooling fan replacement blades (ender series)
thingiverse
I printed the "Cooling fan replacement blades" of the author CreativeTools. But It was too big. https://www.thingiverse.com/thing:186979 The other blades model I found didnt print well since I had no blades to cool the hotend. I modeled this ring quickly and it fitted Perfectly! the inside of the ring model is 21.8mm (for clearance to fit in 21.6) the outside of the model is near to 24.9mm (for clearance to fit in fans ring) is has a diminishing taper angle of 1º so in that way will get tight with preasure There is an advantage of having an intermediate ring. It has enough friction to function, and also will slip If I put my tweezers in there again. or that is the Idea
