LDO Voron Trident 300 Cube 3D Printer Kit (Rev. D)

The Voron Trident is an open source CoreXY printer from the Voron Design project, built around a fixed gantry where the bed moves on three independently driven leadscrews. It's designed for speed, rigidity and straightforward maintenance, and the fully enclosed chamber suits ABS, ASA, and other high-temp engineering materials.

This is the latest Rev. D kit from LDO, designed to improve the most error-prone parts of a Voron build. That means pre-cut and pre-terminated wiring, a Nitehawk-SB PCB toolhead, and the touchscreen, chamber lighting, and stainless steel rails are all in the box. Your time goes into mechanical assembly and tuning rather than measuring and crimping.

Files and the official assembly manual can be found on the Voron Trident GitHub page

Why "300 Cube"?

A standard Voron Trident built to the BOM is 250 mm tall in the Z axis no matter which XY size is picked.

LDO takes the 300 mm XY variant and extends the Z to match, so this kit gives you a genuine 300 × 300 × 300 mm cube. The frame extrusions, linear rails, panels, and cast aluminum bed are all cut and specified for the taller build, so nothing needs modification and no substitutions are required. One size, one configuration.

LDO Rev. D Improvements

What the LDO edition changes compared to a self-sourced Trident.

• Stainless steel linear rails. LDO MGN12H and MGN9H rails in stainless, for better corrosion resistance and long-term stability in a heated, enclosed chamber.
• Nitehawk-SB toolhead PCB. Toolhead wiring runs over a single USB cable to the board rather than a full loom, which cuts assembly time and makes hotend swaps and servicing much faster.
• Pre-cut, pre-terminated wiring. Harnesses arrive cut to length with connectors already crimped, and LDO publishes a routing guide to go with them. Very little measuring, and far less rework.
• Touchscreen with KlipperScreen. A 4.3 inch capacitive DSI display for setup, tuning, and day-to-day control at the machine.
• COB LED chamber lighting. Two 35 cm light strips included for clear visibility inside of the 3D printer.
• Nevermore Micro V5 and Klicky parts included. The hardware for two of the most common Trident mods ship with the kit.

Three leadscrews, fixed gantry

The Trident Layout

The gantry is bolted to the frame and never moves in Z. Instead the bed is carried on three leadscrews, each with its own motor. Klipper probes the bed and drives the three screws independently to bring the plate parallel with the gantry, so tramming happens in software at the start of a print run.

With no flying gantry to keep square, there is less re-calibration needed over time. It's the more approachable of the two enclosed Voron designs, while keeping the same CoreXY motion and toolhead.

Before you order

Printed Parts Not Included

The Trident needs a full set of printed parts. ABS or ASA is the recommended material, ideal for the heat resistance in an enclosed chamber. LDO does however supply some kit-specific prints, including the Leviathan brackets, Nitehawk adapter mount, cable anchors, and LED diffuser. For the rest, LDO publishes a Printed Parts Guide with settings and a full checklist. Start those prints the day you order so the are ready when the kit arrives.

Alternatively, we offer a Voron Trident Printed Parts Kit from Bounty3D, made to order. Printed in Fusion Filaments ABS with a black primary and your choice of accent color, dimensionally accurate for clean assembly, with mounts for both generic and IGUS cable chains. This is the functional set that gets the machine to a running state. Skirts, hinges, and other cosmetic parts are then printed on your finished Trident.

Open Source Design

The Trident is an official Voron Design. CAD, STLs, and the assembly manual are all public on GitHub, and the design has years of community development and documentation behind it.

It runs Klipper, so the macros, web interfaces, and tuning workflows used across the wider Voron ecosystem apply here without modification. Nothing is vendor locked, every part can be sourced and replaced.
