I'm planning to print using a public 3D printer (Ultimaker 3) and was wondering if my settings will work. There is a 4 hour time limit. The parts don't need to be strong.

I've provided some screenshots of the model I'm planning to print and of the settings I'm planning to use. Dimensions of the print are 61.1 x 75.0 x 50.0 mm. Filament is PLA. Also if there is still something I can do to speed up the print, I'm happy to hear your suggestions.
