Where to buy the extruder cover for the CFS upgrade on the K1?

Hi everyone, I’m looking for the part shown in the image below — it’s the extruder cover from the CFS upgrade for the Creality K1. Does anyone know where I can buy it? I’m based in Brazil, but I’m open to international sellers as long as they ship here. If you’ve purchased this part before or know where it’s available, I’d really appreciate your help!

Thanks in advance!
