Other handed direct drive 1.75mm bowden extruder. Also use for c

pinshape

My latest direct drive extruder upgrade is a significant improvement over my initial version, where I botched the handedness of the mounting. This new design features a cleverly integrated funnel in the arm that allows you to easily insert a small sponge or cloth to clean the filament as it enters the system. The bearing end of the arm has also been subtly curved to provide an even tighter grip on the extruder's components. One of its standout features is its ability to drive nylon filaments with ease, even when paired with a stiff spring. This results in remarkably quiet operation, perfect for applications where noise needs to be kept to a minimum. To build this extruder, you'll need the following parts: * A 9x4x4mm ball bearing (available at HobbyKing) * A 10mm fine pitch bowden clamp for 4mm OD tube (found on RobotDigg) * A long direct drive Nema 17 stepper motor with 400 steps per revolution and low voltage requirements (available from OMC-Stepper) Note that the bearing cavity includes 0.75mm thick supports, which must be carefully removed using sharp side cutters before assembly.
