Baikal MP-651K Magnetic Plug For Egonomic Grip

edit: added V3, when resizing the hole to make the plug I made an error. I needed it to be 95% as wide and I assumed it should also be 95% as long, but this is incorrect and the plug is therefore approx. 2mm shorter than it should have been ... I've stretched V2 a bit (98%) and V3 should have a better fit. The holes for the magnet are a bit sreched now, but this is ok since glue needs to go around the magnets.

This grip turned out to fit on my Baikal.
