I bought these heaters by mistake...
[
www.amazon.com]
They are 30mm long and not the 20mm a lot of hot ends uses. The cost of returning them is just about the same as the cost I paid so I decided not to return them but don't want them sitting in my junk drawer doing nothing. So if you have a need for these heaters, you can have them for the price of shipping. $4 for First Class and $8 for Priority.
