Printer platform top view:
|)-()-()-()< (laying joints: Hard to clean, a few joints broken, but 0.6 Scale looks nice too)
|)-=-==< (Standing joints: Easy to clean, haven't tried it at 0.6 yet)
Base part broke, I will reprint tomorrow, version 4 has a thicker base axis.
Use netfabb or simlar to clean the print, or use "print unsolid model" on the UP software dialog.
