Hello. I sent an email to creality support, but I figured I’d say everything I told them here. Hello creality support team. About a year ago I got an Ender 3 v3 corexz. It’s been an amazing first printer, and I think it was perfect for me. But recently, I noticed some problems with it extruding. I finally dug in after it wouldn’t extrude at all. I found a tooth that had broken off of one of the extruder gears, and was getting chewed on by the extruder. (Shown in the photo) I found a replacement extruder that is for my printer on the creality store, but I was wondering if it is possible to buy just the extruder gears, and replace those. Any insight would be helpful thank you.
