OK, possibly should've used more infill if I wanted to use these for anything structural but 10% worked fine.
Using Filamentive rPLA, 195C hotend, 50C bed. 50mm/s print speed. I cannot recommend this filament enough, it flows beautifully!
Tolerance set to 0.3 - will try 0.25 next but wanted a successful print first ;-)
Sliced using Cura 2.7.0 and I should point out that the z-hop function seems to be serving me well...play around with it; it may add a few mins to a print but seems to help a ton with multi-travel prints (where the head has to jump between different places to print).
This worked straight off the build-plate with no extra force needed so will probably attempt a 0.25 tolerance next.
