A4T Toolhead Kit by HoneyBadger

Voron front rail printer builders face challenges assembling a reliable 4010 blower-based toolhead, where missing or incorrect hardware can cause poor cooling performance and print defects. Without the proper fasteners and LED components, toolhead installation can be incomplete, risking print quality and maintenance issues.

The A4T Toolhead Kit by HoneyBadger provides all essential hardware to assemble the A4T toolhead, designed specifically for Voron 2.4 and similar front rail CoreXY printers. This kit includes precision M2.5 and M3 fasteners, standoffs, and SK6812 LEDs for integrated lighting, ensuring a secure and clean installation. It requires pairing with HoneyBadger 12k rpm 4010 blower fans and a 2510 axial fan (sold separately) to complete the cooling setup. The kit supports efficient ducting and easy assembly favored by the Voron community and Armchair Heavy Industries designs.

Why Upgrade?
