Micro 4/3 to M42

I don't know how to properly edit stl's so i could only fix [this](https://imgur.com/a/NEuzAp3) from the remix of the original, but the hole for the pin was too small and had to manually make it bigger. and all works!
Note; It fits on a Olympus, but might not fit on a Lumix or other since the fins are sized ever so slightly different on different camera brands. Should work tho, worse case you file down the fins just a tad. Tested with a HELIOS-44-2 and a INDUSTAR-55-2
