Black Diamond Camalot Trigger Bar Replacements: Recommended 3D Files?

I have two Camalots with broken trigger bars that need replacement: 

1.) a #1 C4 (red) from I believe 2013.

2.) an older pre-C4 single stem (from late 90s? This one has no plastic or metal trigger keeper band on the stem, so likely the earlier variant). Both triggers are similar in profile but slightly different in size, if that matters).

I have a friend with a 3D printer (and know nothing about them or their file formats, compatibilities, etc.) who I'm going to implore upon to print them out. I assume there's plans for a 'snap together' trigger that's easy to install and desn't look too wonky or ghetto.

Can anyone recommend the files to use? 

Thanks a bunch!

Has anyone here printed out a 3D Camalot trigger replacement?

Bump.

this could be what youre looking for. you could reach out to them

Nah, that appears to be someone with a plan to design, fabricate, and commercially sell trigger kits from earlier this year ... their website is defunct. 

I'm looking for a freely offered/public domain .step file that my friend can print out.

Make sure your friend prints these parts in PA, PA-CF, ASA, or some other strong engineering filament, not PLA! And be ready for part failure. FDM printed parts fail along layer lines, often without warning.
