Dasaki MK8ish Direct Drive Extruder for Prusa i3 (MK7 drive gear)

cults3d

Extruder based on the mechanics of the MK8 aluminium extruder for Nema 17 motors. There are two versions depending on the filament used. Each version has two options: one with the motor pointing to the left and another with the motor pointing to the right. This design allows a clear and nice view of the filament input hole. It also includes a filament guide/pressure adjustment mechanism, which can be secured in place using some glue on the M4 screw. Additional receptacles for captive nuts are provided so you can attach your own equipment, such as depth probes or fans. No supports are required because they are included in the 3D models. To complete this extruder, you will need a hobbed Drive Gear (MK7 with an approximate diameter of 10.56mm, suitable for MK8 drive gears and accompanied by the following hardware: 1x 623 bearing, 1x M4x10mm-15mm screw with a hexagonal head (knob), 1x M4 nut (knob holder), 2x M3x30mm screws (motor/assembly), 1x M3x10mm screw (bearing), and 3x M3x25mm screws (motor/filament guide).
