Extruder no push fit connection for NEMA-17 motor with integrated Planetary gearbox

myminifactory

This is a compact extruder requiring no push fit connection. It's designed for the NEMA-17 motor paired with an integrated Planetary gearbox and a spur gear featuring an outer diameter of 16mm at most. I had grown tired of bowden tubes consistently popping out of their connectors, so I created an extruder that eliminated this issue altogether. All you need to do is screw an M4 nut onto the end, then trim any excess tube below the nut using a hacksaw or other cutting tool. Next, use an M2.5 drill bit to carefully remove some material from the tube near the nut, allowing for smooth filament feed. Simply slot the tube/nut assembly into place within the extruder and secure it with clamps. To attach this extruder to the motor/gearbox, you'll need a few specific components: * Two M3x8 bolts * Three M3x25 bolts * One M3x16 bolt * One M4x20 bolt * Six M3 washers * One M5 washer * One M3 Nylock nut * One M5 Nylock Nut * One Bearing 625ZZ (diameter: 16mm, hole: 5mm, thickness: 5mm)
