美国采购需求：Diy 3d 打印机、桌面 3d 打印机、消费类 3d 打印机、3d 材料、3d 耗材、3d 打印机耗材

I recently purchased a dual extruder single nozzle hybrid multi-color printer and it came with two complete hotends. To ensure I have enough backups for my projects, I'm looking to buy a few additional hotends. I've searched online but haven't been able to find any options available for purchase. Could you please let me know if you have these hotends in stock or if you can help me source some? Thanks for your assistance!
