Extruder Knob/Valve/Wheel.
Description
I love the looks of the original but it's slightly too big to use comfortably on the Ender 3 with the Z-screw so close, and it is quite sharp and crude as it has no chamfers on the edges. So, I decided to brush up on my Fusion 360 skills and recreate it with the tweaks I wanted. Ended up with three variants, the largest one is 40mm, medium is 35mm, and the smallest is 30mm. The hole is supposed to be tapered for a good push fit, but it really is quite tricky at these sizes as even the tiniest amount of over/under-extrusion will mess it up. If needed though. it's a good thing these are tiny so scaling and reprinting doesn't waste much. --- Fusion 360 project file included, once thingiverse decides it would like to show it as well.
