Canon EF-M to M39 / L39 Adapter

I had an old Russian camera with a M39 lens and I recently bought a canon M50 and I decided to use the old lens on my camera to have some fun. Because EF-M mount is not that popular there were no adapters so I decided to make my own using two adapters from the comunity (links included).
The adapter is not perfect, but it is usable. First of all, it is pretty ugly. I may re-print it in gold. More importantly, the EF-M mount is pretty loose, so I used 4 layers of 3M duct tape (any brand is fine, but for this brand, 4 layers is perfect as I tried 3 and 5 layers and it did not fit. See last photo). The last big problem is the added flange distance, which is too short, so you can't focus very close.
All in all, I am happy of how this little adapter came out.
Edit 2020-01-05: I updated the stl file. The flange distance should now be correct. Haven't tried it yet,
Edit 2020-01-12: I plan on making a tilt shift version of this adapter. Stay tuned!
