Any type K thermocouple with a ring on the end will do.

Such as http://m.ebay.com.au/itm/800-Celsius-9mm-x-5mm-Probe-Ring-6-6Ft-K-Type-Thermocouple-Temperature-Sensor-/301420546373?nav=SEARCH

This is the exact same kind, complete with the braided steel sheathing: Mini Solar Toy DIY Car Children Educational Puzzle IQ Gadget Hobby Robot M2 2pcs for sale online | eBay

You can find a lot of other direct replacement parts from that seller for the CTC Bizer and other Makerbot Replicator 1 clones.

However, if your printer is still within the warranty period, you might try asking your seller. I had a thermocouple go after I’d had mine for like 6 months, and I got a replacement part for the cost of postage. (The printer should come with a 1-year warranty)

Yes. That’s right. The one picture here is the one I’ve been using for a while now. Works really good. Just make sure you wire it right.
