Took me a few tries but got it going, great stl.
i3 MK2 MMU
Very nice. You printed first version. When I designed it, I made mistake, the red stripes are iin the wrong place and stars are not aligned. I've deleted the old files and all the pictures and put new STL and new srl in Hope not many people woud print it I'm sorry. It still looks great.
I will print the 2nd version too! I was so excited when I saw it I started working to get it printed almost same day you posted it. I still think it is great like you said, keep up the good work. Love having MMU items to print.
