thingiverse

Production Release on an all-in-one BMG Extruder for the Prusa MK3. This mod was designed as a simpler solution to https://www.thingiverse.com/thing:3165551, aimed at reducing inconsistent extrusion issues. This part has two main components: the Main Body and the Top Cover. This design makes assembly and disassembly easier. To complete this build, you will need: 1. One Pancake Stepper Motor with a minimum of 16N torque; I am using a MOONS MS17HD5P4100. 2. Two 5x8x2.5 Bearings 3. One 1.75 / 5.0 Bondtech Drivergear kit (or use the ones that come with your MK3) 4. One Shaft Assembly 5. One Motor Gear 6. One 3x32 mm Shaft 7.
