Spring Suspension

This little spring suspension is a remix of:
[Spring Flinger](https://www.thingiverse.com/thing:2367861) by [BitsnBolts](https://www.thingiverse.com/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](https://www.thingiverse.com/thing:1258690) by [Neubots](https://www.thingiverse.com/Neubots)

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