I saw that design a month or so ago. However, based on the state of the kit I bought with the whole confusion between direct drive and Bowden and the crappy performance of extruder design, I wouldn't recommend that to anyone as a complete kit. It looks interesting, but I'm doubtful it will be delivered as a full kit without issues and recreating some of the metal parts could be tricky. Just because it's all metal doesn't necessarily mean it's better although it is interesting it is supplied with a MKS Base instead of the ramps board if you believe the description.
