Saw this on reddit and figured it would be of interest to some folks here,

Quote:
This is the male portion of the mount that is attached to the rear of a Micro Four Thirds lens. Dimensions were taken from the lumix G Vario 45-200mm f4-5.6 lens mount, measured by myself and my trusty 4 decimal Mitutoyo caliper. The CAD was composed in Solidworks 2013. There are STL and IGS files available. That render was composed in Keyshot.

... There are the technical drawings as well! So if you find an old school machinist whose better than using 1s and 0s, you're still covered.

Oh help me GODs of the internationally standardized METRICAL system, it is in ... INCHES!!! Twisted Evil

Americans often seem to be on a different planet. Smile Their 'world series' is America only & they tend not to like international! The ASTM frequently updates ISO standardized methods unilaterally...

IIRC there have been several multi million (billion?) dollar errors made in space science by mixing metric & imperial units. I think the scientist have switched to metric but the engineers often haven't.

Inches explains why 4 decimals are needed!! It's very rare to need more than 2 decimals when working in mm Smile
It does have quite a few measurements I've not made on my mounts (such as screw holes) & the angles are going to be useful.

Despite the archaic units I'm sure this file will be useful. TFS @fuzzywuzzy !

Even in Canada a lot of industrial stuff is still in Imperial (or as my dad says, "Standard") measurements.

When dad was doing an alignment etc. the tolerance was always measured in "thou".
