thingiverse

Newly designed MB PLUS is a low cost metal hotend featuring PTFE lined stainless barrel that ensures trouble free, low friction filament flow. The hotend is optimized for 1.75mm filament and has a standard nozzle orifice diameter of 0.4mm. This compact hotend is compatible with multiple makerbot-like china-made nozzles from Flashforge, CTC, Mbot3d and other brands, offering a variety of nozzle orifice diameters. A straightforward assembly makes the MB PLUS a great option for hobbyists and professionals alike. The mounting bracket utilizes the J-Head compatible groove mount, allowing for seamless integration with your 3D printer. Suggested methods for thermistor mounting include JB Weld steel epoxy or kapton tape, which ensure secure connection. Efficient cooling is provided by a compact 30x30x10mm fan and accompanying 3D printed fan duct, minimizing thermal buildup during prolonged operation. For optimal results, please note that the MB PLUS requires an operational fan for normal functioning. This hotend's design draws inspiration from Makerbot MK7 stepstruder components as well as several custom-designed parts. Detailed dimensional drawings can be found in the download section for reference and assembly guidance. The complete MB Plus kit is available without fan-duct at www.ebay.com/itm/321602397864
