The file 'Textured G19 To G26 Magazine Adapter 3D Printer Model' is (stl) file type, size is 21.0MB.
Remix of https://www.thingiverse.com/thing:4787965 It would not allow me to tag it as a remix.
I suggest making it 3mm taller on the Z-axis and sanding it to fit tight, I don't like wobble, and that is what I did.
