    Please put these back in the shop. I have been doing a lot of research online and there are A LOT of people trying to find them that are more than willing to pay. Please please please!

    Anybody had any luck with how or where to purchase these things?

    When I call nobody answers.

    Or has anyone just bought the e3d?

    Thanks!

    I've only ever seen the official R1+ heating core and thermistor one place:

    https://www.partsbuilt.com/r1-heater-cartridge-robo-3d/

    https://www.partsbuilt.com/r1-thermistor-robo-3d/

    They're way more expensive there than they should be -- $20 to get one thermistor shipped.

    Alternatively, you can search Amazon for "NTC 3950 100K Thermistor" -- they're not the original but they work and they're super cheap, like a buck per. Note one significant caveat however -- I have not been able to find an appropriate replacement thermistor in a tiny metal can like the OEM part, they're all just bare glass beads or really long cans. I have not tried the long can versions to see if they fit. And since the R1+ holds the thermistor directly in place by a set screw, it's very easy to break the fragile glass bead. Still, even if you break four or five of them before getting one to sit nicely, it's much cheaper than the above option.
