  • At $11.99 for such a small amount, I think it’s better to just order from China and wait. Order a bunch so you have plenty on hand. I ordered some and cut one piece so far, and it looks like I have enough to cut plenty more if needed.

  • Does McMaster-Carr have a local office in Nashville?

  • Thanks! That would be great. :slight_smile:

  • Does anyone in the Nashville area have an extra 12v 40w ceramic heater cartridge for the printer’s hot end? I have one coming in the mail and I can replace yours. Please let me know. I should have your replacement by Saturday. Thanks.
