Minolta M/MD to Nikon F converter
First of all, full disclaimer - this thing is a violation against nature and whichever god/gods of photography you worship. https://www.thingiverse.com/thing:4099515 is completely right in saying there is a reason this thing doesn't exist out there! THAT BEING SAID - I did buy a vivitar micro converter ...with an F mount ...that I intended to use with a 50mm Rokkor ...with an MD mount. The aforementioned existing solution has no stop pins, the flanges are intended to fit really snugly and use friction primarily to hold everything in place. It works, but as some users have pointed out is not exactly optimal. My solution is by no means optimal or arguably better, but at least for my use case which is primarily 1:1 - 1:4 macro it works quite well! I wasn't aware my Saturn V set was THAT dusty...
Not exactly a remix, rather uses parts of https://www.thingiverse.com/thing:5020659 for the F male part, couldn't be bothered designing my own as I know this one works quite well! The female MD came from an MD/Sony E converter that for the life of me I cannot find anymore, will update description if I find the original author.
The primary use here is with a Sony E converter but the thumb grips should clear most camera elements.
