Replacing the hotend on your Elegoo Centauri Carbon or CC2 means wrestling two tiny JST connectors — the thermistor and ceramic heater — back into their ports blind, one at a time, in a cramped space. It's fiddly, it's frustrating, and it's easy to damage the connectors or seat them poorly.

This tool eliminates all of that.

Seat both connectors into the keyed tool — they only go in one correct way — and push once. Both plugs align and seat simultaneously, perfectly, every time. Works equally well for pulling them out.

Use cases: hotend replacement, nozzle swaps requiring hotend removal, and troubleshooting heating errors (Error 103, etc.).

Material: Annealed PETG recommended. The tool can be left on the hotend between uses or removed — your choice.
