J-Struder 1.75mm remix

This is a remix of the J-Struder : 1.75mm Bowden Extruder For NEMA 17 Motor by junaling. Thanks juanling for the original design. I had a problem that after a week the piece behind the spring broke so I added some walls to beef it up and a thumb grip to add to the front when squeezing together. It doesnt just slide together like the original, you have to pop the guide into the base with some force.
