Wobbly,
I modeled them in Blender, and then exported them to *.stl files. I use the CURA slicer. I can export to 3mf, and maybe some others. Give me your email address and I'll send them to you.
I did get a little off on some of my adjustments when modeling, so I had to put in a slight notch for the mag release on the right grip. Other than that, they fit just fine.
