I wanted everything to fit in the compressor so I was limited to only 2 batteries. Im working on putting a larger stronger motor but it will require and external battery park. As for the springs, I thought about using filament but I still print in 3mm. I just got a couple rolls of 1.75 so I might try and make a spring. Probably print a mandrel out of ABS and wrap some warmed up PLA around it.
