A direct drive bowden extruder for 1.75mm and a MK8 style hobbed pulley. The SketchUp Make is almost completely parametrizable, so it can be adjusted to fit other hobbed pulleys as well. I have used a 13x8mm, 5mm bore brass hobbed pulley, because it was easy to acquire in Germany (www.fabber-parts.de).
Parted used:
• 1x Nema 17 stepper motor
• 1x hobbed pulley 13x8mm, 5mm bore or similar
• 1x 5mm OD push-fit bowden connector (add another one for bowden inlet version)
• 1x 604zz bearing
• 1xthreaded rod 1xM4x12mm
• 2x M4 washer
• 1x M5x10mm head screw
• 3x M3x8mm head screws
• 1x M3x30mm head screw
• 5x M3 washers
• 2x compression spring 4mm ID
• 2x M3x50mm head screw with suitable length for the selected spring
• 2XPlates aluminium 6x3x30mm with holes and threads
