Remix for E3V2 Chainmount

I liked the remix of Borszczuk a lot due to the possibility of printing it without support.
However, the STL was a bit inaccurate (like such inaccuracies which happen on Tinkercad etc). They were so big that even in Cura corners appeared which should not be there.
Thats why i cleaned the whole thing up first.

Then i noticed that there is also room for improvement on the rail snapping mechanism imo.
I had a really good one in my printing folders (unluckily i dont know who made it, its also from Thingiverse), so I attached that one.

The whole part now fits perfectly on my setup.

I also added a sample so that you can try out on the rail first without wasting filament.
