[Gulfcoast Robotics] M3 Stud Screw-in thermistor 100K NTC 3950 - Drop in Replacement, Works for Any China 3D Printer extruders - Anet, Wanhao, Maker Select etc.

I was having a lot of thermal runaway issues with the stock glass bead thermistor for the ender 3 Pro. Someone recommended this and I thought I'd give it a try. Works really really well, I particularly like the fact that it comes in a two piece so if it needs to change I don't have to open up and connect to the motherboard. Just unclip from the hotend and that's it.It was a tight fit to put the hot end fan back in place but the screws went in perfectly fine. 10/10 recommend

The thermistor was easy enough to install, even though I was leery about playing with the main board.Additionally, the customer service was great. Had a question they answered within a couple of days.Needless to say I recommend this product and will see what else they have to offer.

Much better than the stock Ender 3 thermistor. Well built, screws right into the hole that the old holing screw was in. Only down side, and not much of one, the wire was too short and I run an SKR board mounted on the left rear, much closer than the original. Just cut your old plug and leave about a 12" solder it to the new wire and your good to go. This is not a cheap replacement like others I've seen, this thing is well built and should last a very long time. I would even recommend replacing it if you do anything to your hot end just to be on the safe side, The factory one is flimsy and if you aren't careful you will break it.

These are great. The only issue i have is the short length of the leads to the JST-xyp connector. There is a mate to the connector included, but in my build it just adds an extra connector to my wiring harness. if the leads were a few inches longer I'g just cut off the existing JST connector and replace it with a JST-XH to allow it to plug right into my harness.

Good enough, needed a replacement.

Printer shut down for E0 temp runaway. Thermistor was reading 0 deg. celsius with a resistance of 3.5 megohms. Should have read 100k at around 23 celsius.

These are great thermistors.. direct replacement for monoprice maker select v2 and wanhoa i3.. way better than the bulb design.. very precise response with little to zero hot end fluctuation..In my opinion this is the best thing to happen to the i3 platform in regards to reliability..

Electrically, these work fine, I've had two. They seem to be a little fragile and the M3 stud doesn't fit all supposedly MK10 extruder blocks. If yours has an unthreaded hole/well next to a clamp screw, chances are this will work. I had to drill and tap an M3 hole next to the M4 hole that came with my cheapy first replacement block, the nozzle threads stripped on the original. Gulfcoast's blocks have the proper holes. My problem was with the fragility of the connections to the stud, I've broken two sets of wires just in normal operation, one in just a week of use. If you never had to dismount the head for cleaning or changing parts, it would probably stand up. As it is, I've gotten a year or better out of the old bead-type thermistors, even with having to clean off plastic globs from non-sticking runs. I'll be sticking with the bead thermistor bundles from here on, if I need a stud mount one, I'll make it from a short brass standoff and some JB Weld. The rest of Gulfcoast's offerings are good, I've bought plenty of their other replacement parts, these just are a little too fragile for my use.
