Direct Extruder Kit — upgrade to reliable direct drive performance for the 5 S1, 3 V3 SE and compatible setups Key benefits Broad compatibility: Designed to integrate with a range of printers, explicitly compatible with the 5 S1 and 3 V3 SE models. Lets you convert Bowdenstyle or stock extruders to a directdrive configuration for improved filament control. Better flexible filament handling: Direct drive placement and positive filament path reduce buckling and feeding issues with flexible materials (TPU, TPE), making flexibleprint projects more reliable. torque, precise control: A matched motor and 51:1 gear ratio deliver torque and extrusion force up to 80 N, improving feed and retraction accuracy for consistent print quality. Consistent, tunable output: Gear reduction smooths filament motion; adjustable tension lets you finetune pressure to suit different filament diameters and stiffness for fewer under or overextrusion artifacts. What it does and why you need it Converts your printer to a directdrive configuration that minimizes filament path length and reduces problems with soft or elastic materials. Increases extrusion force and control for dependable feeding and sharper retraction behavior on detailed prints. Provides an adjustable tension mechanism so you can dial in pressure for PLA, PETG, and flexible filaments without trialanderror hardware swaps. Performance attributes Gear ratio: 51:1 for torque multiplication. Matched motor: tuned to work with the gear reduction to achieve up to 80 N extrusion force. Adjustable tension: lets you set the correct grip and pressure for different filament types and diameters. Gear reduction mechanism: smooths drive rotation for uniform filament delivery. Practical use scenarios Printing flexible phone cases or wearable parts in TPU where a short, controlled filament path prevents jams and improves surface finish. Small, detailed mechanical parts that require precise retraction to avoid stringing and blobbing. Rapid prototyping with mixed materials when you need consistent feed pressure across PLA, PETG, and softer filaments. What to expect Improved reliability with flexible and standard filaments. More consistent extrusion and retraction behavior thanks to a torque drive and gear reduction. Finetunable tension to accommodate filament variance without modifying the material or print settings extensively. Compatibility note Works seamlessly with the 5 S1 and 3 V3 SE models and is intended for use where a directdrive extruder can be mounted or adapted to the printer. Follow your printer's assembly guidelines for installation.
