Flat face - No Support needed.

Horns created to be used in most helmets, may not fit all the models, since the helmets curves are not universal, but most helmets may fit well or with small adjusts.Place them with some strong glue or double-sided tape (use strong ones, preference to originals)

Biggest Horn Size: 63x40x13mm

About resizing: feel free to resize, but note that it may interfere in the curvature of the fixing part on helmet.

I would use this settings, printing in PLA:-Dynamic Quality: 0.16 or 0.20mm-Printing Temperature: 220 (230 for V-Silk)-Build Plate Temperature: 60-70-Speed: it depends on your printer, but use the standard you use often-Build Plate Adhesion Type: NoneBut feel free to change and use the settings you prefer.Every printer has different settings that works better, so use the one you already use.Its a very simple model to print, so feel free to use the settings you are used to.
