Very nice! I plan to eventually modify my voxel ox into this setup. I opted for my Z screws to go at the sides though, similar to a previous build on here and at first glance I couldn't find a closed loop belt with the dimensions I need. This is my first 3D printer though, so I will probably revisit the idea once I've smoothed over my current printing issues. Out of interest, what size is the belt you are using? On another point, Absolutely loving this printer. I've had minimal issues in setting it up, which is in no small part to its brilliant design. The only issues I've had have been made by myself to be honest where I have tried to skimp on expensive openbuilds parts. Unfortunately we pay a hefty shipping rate in the UK to get V-slot and simple things like the wheels soon becomes one of the greatest costs.
