Elegoo CC / CC2 Hotend Plug Tool — Align & Seat Both Connectors in One Push

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 crooked.

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.

Problem solved: The Elegoo Centauri Carbon toolhead provides extremely limited access to the thermocouple and heater power receptacles during hotend changes. This tool holds both male connectors as a single aligned unit with a 25mm handle, providing the reach and alignment needed to seat the connectors with minimal effort. The tool can remain semi-permanently attached to the hotend for easy reconnection.
