Principles
Built for real workshops
Parts people can source, and tolerances a good shop can hold.
One design, one repository
Every design stands alone, with the same structure so anyone can find their way.
Credited and licensed
Every contributor is named, and every design carries an open license.
Open to contribution
Issues, improvements and field reports are welcome on every repository.
