Tevo Tornado Fang with slotted mounting holes without Bl-touch mount

I had issues with the "Fangs" scrubbing my printed parts, so I slotted the mounting holes. I printed this with the following settings in Cura on my Tornado with excellent results:

Layer Height: 0.3
Wall Thickness: 0.8
Top/Bottom Thickness: 0.8
Infill: 20%
Grid pattern
60mm/s print speed
Brim 4.0
I used triangles for support
50 deg angle
15% density
