I ended up using as much metal bracing as possible instead of the 3d printed parts (All printed parts were made with PETG). Also, I replaced the z axis wheel mounts with OpenBuilds aluminum plates / eccentric spacers and it's super stable now. Still waiting for my aluminum plate / silicone heating pad to come in the mail, but I've done some test (no filament) prints and everything looks to be running well. I did notice a lot of vibration in vertical extrusion near the x/ y motors (due to how tall I made it). I added some 45 degree bracing on the sides and it removed most of the vibration.
I hope to be printing in PLA (no heater) this weekend!

Double D-Bot 400mm x 400mm x 600mm
Based on D-Bot but used more metal bracing / openbuild plates instead of plastic parts. Also size was increased.

Reason for this BuildStarted with a smaller basic Prussia I3 printer, but quickly realized I needed something larger. Really liked the D-bot design
