This project has been killed and i recommend anyone avoid attempting to make it. A few reasons why mainly due to function and compatibility,
this was originally the first thing i designed when i got into cad thus seriously lacked simplicity and while it does work its far to finicky / complex to get working as well as riddled with compatibility issues. This project is just far to complex to get working for the vast majority of people due to some of the step requiring fine tuning like for example filing disconnector and tuning the hit arms. The super safety while prone to wear when printed is far superior in all ways so that method of "FRT" will be used going forward.
Also there are some arguments as to the legal side of this trigger due to its use of m16 parts and thus only adds to my "just print a super safety" recommendation.
I will leave the files uploaded as i know older versions will just be reposted and id rather you at least get them from me if you must attempt to make this.
