Ender-2 Big leveling knob

thingiverse

This is my inaugural project in Fusion 360 and the first part that I'm publishing on Thingiverse. It's a remix of thing:2529739, but with a significant upgrade - this knob measures 36mm in diameter instead of 28.5mm, providing ample clearance for the "Y-switch end stop cover" thing:2829876. What's more, this design doesn't require any supports to print successfully. It fits snugly on all three knobs of the Ender-2. To install it, you'll need to remove the existing knob first since this part is specifically designed to be mounted on top of the knob. I've included STL, STEP, and Fusion 360 files for the Creality knob as well (with my own measurements). One area where my prints fall short is the surface finish on the spokes, which can appear uneven at times. I use PLA with a hotbed temperature of 50C and a hot end temperature of 200C without part cooling (I'm still waiting to set up part cooling). Any suggestions for improving my print quality would be greatly appreciated. This modified knob should fit most Creality printers, including the Ender-2, Ender-3, and CR-10. A major advantage of this design is that it's much easier to access the knob from inside. To give you a better idea of how this design compares to others, I've included pictures of various knobs - the original Creality knob, thing:2350483, thing:2529739, and my own creation.
