Bathroom Fan Grill

Summary Created this for a friend of mine for the bathroom fan. I'd probably slant the slots if I were to modify it, haven't done it yet :D If anyone wants to remix, I've supplied the fusion 360 files - please just let me know what you do with it should you tweak :D Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: No Resolution: 0.100 micron Infill: 25% Notes: Since there is some clamping force required for the corner holes I wouldn't print any less than 25% infill, perhaps add more shells to see how much less infill you could use? Print face down at the highest resolution your printer supports for best results on the corner holes which are countersunk.
