Elegoo Centauri Carbon Handle w/ Lid Prop Print in Place

Replacement Handle for the Elegoo Centauri Carbon (Print‑in‑Place Hinge + Door Prop)

This is a print‑in‑place replacement handle designed specifically for the Elegoo Centauri Carbon 3D printer. The shape is inspired by the Elegoo logo, and the hinge mechanism allows the handle to double as a door‑prop to keep the front glass cracked open for ventilation during prints.

Key Features

• Fully print‑in‑place hinge — no assembly required

• Dual‑purpose design — standard handle + door‑prop for venting

• Fast print — completes in just over an hour

• Magnet‑assisted closure — uses (2×) 4 mm × 2 mm magnets to keep the handle closed

• Secure open position — (2×) M3 nuts embedded in the ends provide attraction points for the magnets when the handle is flipped open

• Centauri Carbon text embossed on the front

• Minimal supports — designed for auto tree supports only

Design Notes

Earlier prototypes included small locating cylinders around the screw holes that keyed into the glass door. In practice, those tiny posts were fragile and often snapped during installation, forcing me to hold the broken piece with needle‑nose pliers while backing the screw out. The final version removes those posts entirely for a smoother, frustration‑free install.

Color Options

My photos show the handle printed in Anycubic Pearl Black, which makes the front text subtle in pictures but very clean in person.

Two versions are included:

1. Standard Version (for Centauri Carbon)

The Centauri Carbon can’t print multi‑color in a single pass, but you can add color by:

• Using a filament swap at the text layer

• Printing a colored inlay behind the black top surface

• Modifying the included STEP files to create your own embossed or recessed color strategy

2. AMS‑Friendly Version

This variant has the front text fully filled so AMS printers can easily print the lettering in a contrasting color. The example image shows Anycubic Pearl Black PLA with an Eryone Dark Grey Carbon Fiber PETG inlay.

Printing Recommendations

• Material: PLA, PETG, ASA — all work

• Supports: Enable auto tree supports (very minimal)

• Magnets: 4 mm × 2 mm round

• Hardware: Standard M3 nuts (2×)

This design is inspired by the general concept of a door‑prop handle, originally seen on a MakerWorld model for the Bambu P1S/X1C. This version is an original design created from scratch for the Elegoo Centauri Carbon, using different geometry, hinge structure, and logo‑based styling.
