Titan M4 Thumb screw

Tools and hardware needed:

M4 Nut
M4 Die
Sandpaper or File
Wire cutters or scissors

Print on the flat side, and reduce material around the 4.2mm shaft until it's rounder and the Die is able to begin cutting threads. Then thread as normal. Something like four turns forward, two turns back. Attach M4 nut, and spring and insert into Titan Extruder.
