Crossover Mask from Mad Max 3d modell

Need some supports, but it's really easy to print and the model is fantastic! I printed it 50% sclaed using Prusa Edition Slic3r 0.35 mm settings! P.S. I don't remember printing time.... All 3 models scaled by 50% with 0,35mm took around 9 to 10 hours, maybe less!
