While taking apart the hotends on my PowerSpec Ultra 3D printer (Flashforge Dreamer clone) to clean a plugged-up metal tube that goes on top of the heating block and goes into the hole in the mounting block, I lost one of the plastic spacers that go between the heatsinks and the fans in front of the servo motors. I thought I have extra parts but I can't find them. How can I get spare parts for my printer? I also replaced the nozzles with new ones because one of the was plugged-up. I found out from the Internet that I have to use a torch to burn out the plastic. I don't have a torch.
