My 3d printer stopped working recently, and I narrowed it down to the element, thermistor, or the extruder motor. When I tested the motor, I found it to work, which meant the hot end had to be the culprit. running it by hand, I found that it was only staying warm for a few seconds then it would get too cold to melt PLA causing it to harden and clog in the tip. It was the thermistor. Due to the low cost of this and the blocks, I just rebuilt the entire assembly and got back up and running again. These seem to be high quality,and well made. Fair warning.. the thermistor harness has an end that will not work on an Anet A8, you'll have to do some splicing. ### ⭐⭐⭐ Doing better than expected *by C***S on Reviewed in the United States 🇺🇸 on June 27, 2019* I was worried about using alternative products with my E3D V6, but these are doing alright.If anything, I have two complaints: they use connectors built to plug directly into the TriGorilla board, and at least on my AnyCubic i3, there's a secondary circuit board with different connectors, mounted on the printhead, so I always have to swap out the connectors when replacing cartridges or thermistors.Second: the thermistor is basically naked. The copper wire is inside a tiny glass (?) bead, while the E3D block is built for a little copper jacketed cartridge, so getting placement right without pinching the wires or getting wildly inaccurate readings is a bit of a challenge.But overall for the price and volume, an admirable little kit. ### ⭐⭐⭐⭐ Does the job *by D***C on Reviewed in the United States 🇺🇸 on August 4, 2020* They fit and do the job, that is all I ask since heaters burn out all the time. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/46347177-ewigkeit-12v-40w-ceramic-cartridge-heater-and-3950-100k-ntc](https://www.desertcart.hr/products/46347177-ewigkeit-12v-40w-ceramic-cartridge-heater-and-3950-100k-ntc) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-16*
