Key Features: High-performance material feeding system with the ability to print faster with improved quality Housing made from nylon for precision and durability Spring loaded pre-tension on the filament. Thumbscrew tensioner allows fine-tuning of the pressure exerted by the drive gears onto the filament. Designed for the Wanhao i3 Bondtech Mini with Dual-Drive gears that grips the filament from both sides without any slippage or grinding as an upgrade kit for the Wanhao i3 printer. The smaller effective diameter of the drivegear will increase the torque by about 50% and also the resolution will increase with 50% since the E-step value is 140 compared with the 96 as the standard extruder.The filament path is fully guided and this makes the extruder work perfect with both hard and soft filaments, the drive gear is also in hardened steel to withstand wear from especially filaments with abrasive additives like carbonfiber and glassfiber. The quick-release lever lets you load and unload filament with ease for quick filament changes.Item Specifics1 - Bondtech Mini Extruder1 - Hardened drivegear in steel2 - Bolts M3x45 mm1 - Aluminum shimDoes not include mounting bracket (sold separately) or motor; can use the original i3 motorMaximum X-movement is restricted about 15 mm on the right side.E-step needs to be adjusted to 140 step/mm (with the LCD panel)Note! The version 2.1 of the Wanhao i3 have a different part cooling fan housing that will make the housing to be lower than the nozzle, a custom printed part cooling fan housing could be used instead.
