I just got a OM-D EM10 and bid on a bunch of cheap Soviet lenses on eBay for fun. Of course didnt research quite enough and ended up with 2 Kiev Contax (EDIT: Meant to say Kiev 10 or Kiev 15, not Contax) lenses (Mir 1 and Jupiter 9).
Since I couldnt find a Kiev 10 to m43 adapter online I made one in Fusion 360 and 3d printed it. Since the aperture adjustment is on an internal bayonet on the Kiev mount I put a little grabby flange inside, when mounting it you spin the lens on still the bayonet embeds into the plastic of the flange when you can spin the lens in/out of the adapter (as if removing or tightening) to change the F stop.
I have no idea if Ive done a good job or not as Im new to all this! Seems to work fine, though my Jupiter 9 is producing strangely warm photos??
The STL's for printing should be up on MyMinifactory soon once it passes review later today:

I put two versions (and a few lens caps) there, one with a "base plate" partially covering the opening to allow easier 3D printing with troublesome filaments. This is just cut off the final print. Most printers can use the standard version.
Oddly tiny photos I have to hand:

Questions for you guys:
- Any tips or changes I should make?
- What effect does the height of the adapter make to the lens and its performance? Via trial and error I made it 26mm (absolute max dimensions, including mounted part in camera).
- Any reason one of my lenses shoots visibly much warmer shots that Im overlooking?
