I recommend Printing this at 103%-104% (at least if using Cura Draft settings). Tried 100 and 101 and could not get it on there printed at 103 it still took a good bit of force.

It's so sad that something like this is even necessary. Did not one person at Creality use this printer after it was first designed? No one cared enough to be like, 'hey guys, this knob sucks. Let's take 5 minutes and design a better one." Must've been the cheapest option so they kept it. Dicks.

It was a complex problem to solve. It took months of calculations and 100s of prototypes for me to solve one of the great mysteries of the Ender/CR-10. Actually it took about an hour and 2 prints to get it right.

How do you remove the original knob?

With a little bit of muscle carefully pull it. There are tight sometimes.

Thanks! Question, do you recommend using supports for the inside of the knob?

I recommend highly against. It is small enough that the top can be bridged fine and getting support out cleanly would be a nightmare at that size.

It has been a while since I made this knob I can not remember. Either way its such a small print try without first.
