Hotend Heater + Thermistor Kit — Runice 24V 70W + 104NT Thermistor Cartridge

The headroom tier: Runice's 70W high-temperature cartridge — the heavily insulated build made for dfh.fm — with the 104NT thermistor cartridge. For big blocks, 300°C-plus materials and the fastest heat-ups, with the spring-relieved, JST-XH-terminated sensor that matches.

What's in the kit

• 1× Runice 24V 70W high-temperature heater cartridge — 6 × 20 mm, 1 m red fiberglass-sleeved leads, tinned ends (P/N 3028-07A)
• 1× Runice 104NT thermistor cartridge — 104GT-2 / 104NT-4-R025H42G class, spring strain relief, 1 m lead, JST-XH

Fits

• Any block with a 6 mm cartridge bore and a 3 mm sensor bore that wants more heater than 60W — large blocks, high-flow hotends, engineering filaments.
• Printing above 300°C? The 70W + PT1000 kit swaps the thermistor for a PT1000.

Gotchas

• 24V only. 2.9 A needs a real connector — Micro-Fit 3.0, screw terminals or the toolhead board's heater terminals, not a JST-XH. PID tune after install.
• Heater block, connectors and silicone sock are not included.
• Same parts, same shelf as the singles linked above — if the kit reads sold out, one of its parts is.
