Any chance you would be willing to share? I just got my Prusa built a few weeks ago...
Not a shareable STL. Too much work was required to prepare for use so it will need to go past prototype seen in photos to have a clear conscience. I've posted WIP
for you to tinker with. But as the warnings show, you'll have to roll up your sleeves on this one. Much luck, hope you can make it work for you as well.
I've also included STEP files of all the gubbins you'll have to negotiate for space. See my photos for how much space and routing for the thick wires there in.
Consider a smaller or pure wire based accessory connector with a gasket/grommet style wire passthrough hole. My design is pretty difficult to work with, had I to do this again, I'd just buy a closed rubber grommet and cut slits to need.
