Tomaskom made a great design and I simply modified it for the U30/LK4 that installs without needing to take anything apart. This one clips onto the top rail. Also added small storage spot on top. When I printed it, the pin wouldnt fit in the roller, so I used a wooden fondue stick and it fit perfectly... looks like most Q Tips could be made to work as well.
I have not tried printing it upright without supports but it might work that way.
