MakerGear M2 Ben Heck Extruder

This is an alternate extruder design for the MakerGear M2 printer, based off the one I bought in 2016.

Uses the existing bearing and bearing shaft. In addition you will need:

(4) M3 10mm socket cap screws
(3) M3/4-40 25mm flat head screws
(3) matching nuts for the above
(1) M3/4-40 10mm flat screw screw
(1) 1/4" x 3/4" threaded aluminum spacer
(1) Size 6-32 1/2" long pan head screw
(1) Size 6-32 1/2" long flat head screw
(8) 8mm X 3mm neodymium magnets
(1) 5/8" x 1" spring
