Microscope lens adapter (M43)

This is a remix of the perfect adapter from thenickdude https://www.thingiverse.com/thing:5130912. I needed to change the barrel to 30mm round to make it possible to slide an adapter for the Metz MS-1 on the tube. While doing so also changed the bayonet mounting indicator to a small protruding half circle like other M43 lenses.
Also tried this microscope lens: https://nl.aliexpress.com/item/1005005792946315.html for 12 euros its a very very nice lens. Even better grab a broken Minolta slide scanner from ebay. Inside is a miracle lens. Probably an apochromat with no CA visible and razor sharp (true achromats have some CA in the bokeh of out of focus area's).
The adapter to mount the minolta lens on the tube is included (and a very basic lens cap)
