Z axis belt is in, just cut out a little housing for the stepper motor that allows me to use it for belt tensioning. Joining the belt was a bit of a pain, originally I tried glue and tape, however that quickly snapped under tension. Instead, I sewed it together, then melted a bit of scrap belt on top, followed by heating a piece of metal and pressing it down on top. This kind of sandwiched and melted everything together. It's holding fine so far, though the teeth are a little unaligned.
