This project was first designed to upgrade a salt spray chamber on Michigan Technological Universities campus. The project has been expanded to convert all designs of the salt spay chamber to open source design.

== Project goals ==

# Plan upgrades
# Execute Upgrades
# Make BOM and instructions for entire chamber
# Profit

== Design ==

All design files are hosted on http://3dprint.nih.gov

== Conclusions ==

This salt spray chamber would save approximately $19,000 from our first rough estimates. Our current modifications now save $475 assuming that just 4 sample racks are needed. These modifications can easily be put into most chambers with only small changes needed. This chamber has no loss in quality, and currently complies with all ASTM standards.
