It worked but the cable that connected to thermistor and main cable to the machine was much too short on the original one. This one is much longer and allowed me to hide the connections in the wire chain. I love the spring around the end of the cable. I love Harding an add bit of protection against stressing the wires or the insulation getting cut or burnt. If you have a hotend this threads into I would recommend it. I have a Aquila S2 that I used this on. It will work on the stock hot end as well as a Haldis 3D Red Lizard Q1 V6 Hotend upgrade. ### ⭐⭐⭐⭐⭐ 1,000 Times Yes! *by M***R on October 13, 2023* Absolutely perfect replacement for the glass bead thermistor that came with my Voxelab Aquila. It comes with a male JST connector, but... the installed connector for the thermistor is male...soo...there I would have to do more cutting and splicing to utilize the JST connector. My only suggestion, include a male and female JST connector or leave the free and tinned.It works GREAT and my thermals are 100% consistent now. This makes way more sense than using the bead anyhow. You're getting full contact with the thermistor and the heatblock. ### ⭐⭐⭐⭐⭐ Works on Ender 3 *by B***N on November 23, 2022* Ender 3 thermistor wire broke and I scoured around to find what was a smart move. Several other "bundles" had serious QC problems. This seemed sensible.Only thing is, that there may be something with thread compatibility or the block on the printer isn't threaded very far. Needless to say I turned till it was ALMOST fully seated, but I got scared it was gonna break on me.Turned machine on, and both temps read the same. Worked great so far. ## Frequently Bought Together - Upgrade M3 Hex Screw in Fixing Thermistor 100K 3950 Temperature Sensor for Ender 3 V2 Pro CR10 and Other 3D Printer Extruder Hotend (100K 3950) - 3D Printer 6x20MM 24V 60W Ender3 High Temperature Heater Cartridge Element Compatible with V6 HOTEND PT100 Volcano MK8 Extruder CR10 Ender 3 V2 Ender 3 Pro 3D Printer (24V 60W) - Comgrow 5PCS Creality 3D Printer NTC Thermistor 100K, NTC 3950 100K ohm Thermistor Temp Sensor for Creality Ender 3/Ender 3 Pro/Ender 3 Neo/Ender 3 Max/Voxelab Aquila XH2.54-2P Connector (1.3m/51.1in) --- ## 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.gr/products/345049650-upgrade-m3-hex-screw-in-fixing-thermistor-100k-3950-temperature](https://www.desertcart.gr/products/345049650-upgrade-m3-hex-screw-in-fixing-thermistor-100k-3950-temperature) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-05*
