At present, only Makergear is stocking these pre-made, but I'd love to see them becoming the standard for new Makerbots. The material is simply superior for extruding ABS. However, for PLA it poses some friction problems, so caveat emptor! I would also love to get a new pulley from Makerbot, but the shipping is far more expensive than the item itself! Any way we could get small items shipped by post instead of pricey packaging? Also, when you do get around to replacing your thermal barrier, get a PEEK barrier instead.

They have that great black PTFE and the blue retainer - that stuff rocks!!! Second hint: Buy some spare parts at *sorry!* MakerGear (check out the “Operator’s Pack”).

This redirects the force of the extruder back to the retainer. Making the retainer the "single point of failure" (but we can live with that! Just print out some more!)
