Combined right mks gen l from https://www.thingiverse.com/thing:3688967
with drag/cable chain connector from https://www.thingiverse.com/thing:3690894
Added the Fusion 360 file, it's just the imported STLs did the "Mesh to Brap", cut the not required items away.
And some images of my installation, I thing I have some Over Extrude going on.
I had some grinding to do to make the 2 cases join and the lids are verrry tide.
I guess I have to make/print a straight bed chain connector too it looks a bit bend.
