@ajroach42 the main issue I could see with this is longevity due to wear on the coil spring
@theoutrider yep! But the spring is made out of abs, and abs is super cheap.
When the spring wears out, you grind it up, extrude it in to new filament and print another, right?
@ajroach42 but yeah, in general that's amazing as a concept
