There is a setting in cura - horizontal expansion? Something like that. It can compensate for all wall thicknesses without you having to modify your STL. It can make all walls thicker. You might have to enter a negative number. I forget what it's called but it's a fun parameter to play with.
Thanks a lot man, horizontal expansion was a game changer. Didn't know about this.
This is what it looks like now:

I have no idea if .25mm nozzle strings more. White filament definitely strings more. I would do a few things.
UM2 can travel up to 300mm/sec. Try at least 200mm/sec. This helps to break the strings.
I'm pretty sure .06mm is worse for stringing. Try .15mm for .25mm nozzle or .2mm layers for .4mm nozzle.

Do not use any support.
Make sure fan is at 100%.
Cooler is better. 195C was smart. 180C smarter. But that might underextrude. You can play with temperature a bit.
Make sure retractions are at max - there is something like "minimum gap for retraction". Set that to 1mm - if the gap to traverse is less than this it won't retract. Also there is something like "minimum extrusion between retractions". If this is too low you can grind the filament but you should be okay. The default retraction is 4.5mm and if you set this to .45mm you will get no more than 10 retractions for every spot of filament. Maybe set this to .1mm so there are more retractions on your model.
Turn off infill. You don't need it and it just makes for more retractions.
