Anyone know where else I can get a hot end cartridge(12v) the diameter of 5mm. (Ubis hot end for Printrbot).

Mine gave out in a month.

Lots of options on ebay:

True, however, these cartridge heaters are 6mm in diameter.

The Printrbot Ubis cartridge heater is 5mm in diameter.

I don’t want to bore out the heater block due to how close the cartridge is to the wall of the block.

RepRapPro do one on emaker - http://www.emakershop.com/browse/listing?l=533

Just fill out a ticket and we’ll replace it free. Sorry to hear if the failure!
