B2D Extruder with gears MK8 (1.75mm)
Description
### Why is it better to use MK8 gears in B2D extruder? **The output geometry of the filament is not much damaged, improving the retract and more uniform melting of the filament when printing. The output diameter of the filament is better (not oval).** ### What is changed? * filament feed is precisely designed for mk8 gears (instead of “40 tooth inner hole 5 diameter 12mm feeding gear”) * reinforced filament clamp * reduced diameter of the filament guide hole (instead of 2.5mm, it became 2mm) * instead of bearings 605zz bearings 625ZZ are used ### What is needed to assemble this extruder? * 2GT-130 6mm width synchro belt x2 * 2GT-20 inner hole 5 synchronous wheel x3 * 2GT-16 inner hole 5 synchronous wheel x1 * MK8 gear x2 * 625ZZ bearings x6 * 624ZZ bearings x2 * Pneumatic fitting PC4-01 x1 or x2(for down guide) * 5*45 pin x2 * 5*30 pin x1 * M3*16 x2 * M3*12 x5 * M3*30 x4 * M3*20 x1 * M3*12 x2 * M3 six angle nut x10 * M4*10 ball head screw x2 * M4 six angle nut x2 * M5*16 countersunk head screw x1 * M5 square nuts x1 * Powerful spring (height 15mm) x1 * M5 washer x5
