There are two kind of files included for each horn:

• Complete Version
• Sliced VersionThe difference here is that the complete version, is to be used if you'd like to print as a single piece, but note that it will require way more support, and its harder to print due to curved surfaces.The sliced version, is sliced in a part that gives one flat face, to be easier to print. Depending on your printer, it may still require some support, but way less.The sliced version includes a rectangle connector to be easier to glue.Also, the sliced version may fit better some printers due to reduce the maximun size of the printing piece.

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

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)

*Some helmets includes a full flat version, which is a third option if you are having difficult in printing it. These third versions usually changes a bit the horn appearance in exchange for making it way easier to print.

All maximun sizes are sliced to fit a 200x200 printer.The full complete horn versions, may be bigger than that, but they are all sliced in a version to fit 200x200

*To check individual sizes, see each horn on my profile and collection.

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.
