This little spring suspension is a remix of: Spring Flinger by BitsnBolts.

I liked how the center rod helped keep things in line.

For my purposes, I needed to things to stay in line but the whole assembly needed to expand and compress. So I added an inner and outer sleeve to slide in a telescoping fashion.

Inspiration also came from: CUSTOMIZABLE Flat Spring by Neubots

The spring was printed with 100% infill. The sleeves were printed with 30% infill.
