Great design!
Have printed it in my HP MJF 580 and it works really great. Is it possible to get a version for 3mm motorscrews and more material around the motormounts for a 6s beast? Or is it possible for you to share the step files?

I created a VTX tray for this one.

Thanks for posting this frame. Just finished building it today and hope to fly it today.
