Hi there !
I just made a new improvement to my U20 ! This improvement is essential if we want: - The settings are more comfortable! - more precise bed adjustment! - No glue or fixing to install it! In addition, this model is extremely solid! I needed to make this improvement because it is a crucial step before making another new one! I'll tell you about it in another video

The STL file is available in video's description !
