Made gaint Companion Cube on our Bukito Portable about 5"x5" (120mm)
Looks very promising. Looking forward to getting mine in February (as long as the schedule holds). 
Very cool hot-end! Is it a aluminium profile as heat spreader?
Print time? 
Not sure time. But about 5 hours at least. Just left it overnight with SD card. Was set to 150mm/sec or more.
That’s too cool
