A semi successful first print. 

My supports are too thin for PETG, causing some problems, so I'm increasing the support materials by 0.4mm.

Lowering the print speed did help with stringing, but caused excessive deformation on the Z scarring area, so I'm keeping the travel speed the same, but increasing the print speed slightly. 

Dimensional accuracy is good, but it's still a bit crooked, so I'm going to edit my model a bit.
