Voron Carbon Fiber X Gantry, 300 spec

Product information "Voron Carbon Fiber X Gantry, 300 spec"

Light weight carbon fiber X gantry replacement for Voron 2 & Trident.

  • much lighter than aluminium extrusion
  • suits MGN12
  • rigid 2mm wall design
  • includes mounting/installation hardware

Please choose the appropriate length tube for your machine and/or see below for more information and technical specifications.

This carbon fiber x gantry replacement was developed after testing and trialing some of the carbon fiber gantry replacement options available in market.


  • 250 spec = 330 mm length
  • 300 spec = 380 mm length
  • 350 spec = 430 mm length


  • much lighter than the aluminium counterpart

  • drop in replacement on all existing spec Voron 2 and Voron Trident models (250 / 300 / 350)
  • adequate mounting holes for MGN12 linear rails
  • adequate access to all rail/top mounting screws / nuts
  • multiple mounting points for chains and alternative toolhead wiring solutions like Roadkill toolhead pcbs using flat/ribbon style cables
  • tested to an operating temperature of 90c

What’s included

  • carbon fibre square tube
  • 2x 250mm length 5mm carbon rod – diameter tolerance of 4.96-4.99mm (for other weight saving projects / mods)
  • 10x M3 flanged and serrated hex nuts (since 16th of March 2023)
  • 10x M5 flanged and serrated hex nuts (since 16th of March 2023)
  • M3 5.5mm hex nut driver (since 16th of March 2023)


Our tube uses the spec Voron mounting pattern / locations for the top and bottom M5 bolts as described in the manual assembly instructions for both Voron 2 and Voron Trident so there is no difference from standard gantry assembly.

The tube is also 2020 in dimension, matching the specced aluminium extrusion and compatible with the rail centering printed parts.

There are 2 changes from standard manual assembly:

  1. Printed hex nut holders are needed and inserted into the square tube to secure and align the hex nuts for the incoming M5 bolts that attach the X gantry to the XY joints.
  2. As the carbon gantry does not have slots or channels in the center of the faces, alternate XY joints are required to be printed that do not have locating notches that usually go into the slot of the aluminium extrusion. These are the stock XY joints with the locating notches removed.

For further modification and weight reduction in addition to the carbon fibre gantry. The pins mod is available here from Woki Leo.


Cutting carbon fiber releases dangerous and harmful particles when cut. Please be aware and take the necessary precautions.

Fermio MGN9H, 50 mm, 440C SUS (silver)
Fermio MGN9H, 50 mm, 440C SUS (silver)
Fermio Labs miniature linear guideway; single rail cut to length with a single long block. Highest preload (Z1) and normal (N) precision guarantees a stiff / play-free and binding-free motion. Unlike most of the linear guideways produced in China, our blocks feature a functional injection hole / grease port for lubrication which is compatible with our lubrication kit. Warranty The blocks and rails are non-interchangeable - keep the blocks on the rails! A violation does expire warranty effectively. Cleaning We strongly recommend to clean the rails before lubrication. Put a zip tie through the very last holes to ensure the block can not escape the rail. Fill a glass with some grease solvent and soak the blocks for at least an hour. Rinse the blocks and wipe the rail from any residue grease with a lint-free cloth. Lubrication We recommend to lubricate the ball races and bearing balls with grease, and cover the entire rail itself in a thin coat of grease to prevent oxidation. Recommended lubricants (in no particular order): CPC Lubrication Kit 18G Fuchs Planto Multispray S Fuchs Lagermeister BF2 Mobilux EP 1 or EP 2 HIWIN G05 Note: lubricants containing MoS2 or graphite must not be used.

Keenovo Silicone Heatmat, 290 x 290mm, 230 V/AC, 400 W
Keenovo Silicone Heatmat, 290 x 290mm, 230 V/AC, 400 W
The silicone heatmats were custom designed by Fermio Labs and made to spec by Keenovo. All heaters are optimized for our build plates shapes and hole positions. They allow even heating almost all the way to the edges of the build plate. The power is adjusted to allow running them at 100 % power without risking damage to the build plate instead of the 50% to 80% PWM limit recommended for the heaters listed on the BOM. The standard DIN466 thumb nuts used in all Voron printers used as spacers (VORON2) or levelling nuts (Trident, VORON0 and VORON1) can be used as guides to align the heater. For added safety all heaters come with a self resetting bi-metal 150C thermostat. This turns off the heater if temperatures reaches 150 C due to technical failure of your electronics (only meant as a safety feature, not for temperature regulation). Thermistor used is a NTC 100K thermistor (Beta 25/50 3950K-1%, click here for the R-T datasheet) Choose type 11 or 13 in Marlin firmware. Use "Generic 3950" in Klipper.
