Lewihe PLAY stronger Y ends

Well. I knew for a while that there were a new design for the parts of the lewihe play. I could only see pics, Couldn't find the designs anywere. Anyway the thing that makes more sense to me was the stronger Y axis ends. As I had no design sources (just the stls for the old parts) I took the .stls and made some quick and dirty changes to them to allow for a stronger grip of the screws. This way the screws are keeping its axis with TWO support points instead of just one. Undoubtfuly stronger. Thi
