I found that when printing a larger set of these, I would get really fine strings between the parts.
So I played with the settings some more.
Retraction Distance: 5mm
Extra Retraction Start: 0mm
Retraction Vertical Lift: 0.5mm
Retraction Speed: 2000 mm/min
Coasting Distance: 2.0mm
Wipe Distance: 6.0mm
Layer Height: 0.15mm
Top Layers: 3
Bottom Layers: 3
Shells: 2
Out Line Direction: Print Inside-Out
Print island sequential with out optimization: On
Use Random Start Points for All Perimeters: On
No Supports
Extruder Temp: 237c
Bed Temp: 70c
Fans turn on at layer 8
Fan speed: 50%
Default Printing Speed: 3000 mm/min
Outline Underspeed: 65%
Solid Infill Underspeed 70%
X/Y Axis Movement Speed: 6000mm/min
Only Retract when crossing open spaces: On
Force Retraction between layers: Off
Minimum travel for retraction: 0.02mm
Perform Retraction during wipe movement: Off
Only wipe extruder for outer most perimeters: Off
Here are the results:

For more reliable/consistent prints, I'd recommend leaving retraction enabled, but setting retraction distance to 0.0mm and making sure your movement settings are as fast as they can be. As well as lubricating your rods.
I think a z-hop of 1mm when retracting will be fine. I print without fans, and I had better results going shorter - around 0.25mm.
