Quick Chevron I cooked up for my staff (E-9 Master Gunnery Sergeant).

You could also make this a service uniform style by using green and red.

If you're savvy with the ironing setting, Id apply it here.

***print profile speeds are very low since I used gold silk, change them back to your desired speeds to decrease print time***

Filament Used:

Red brick MATTE PLA from Overture

Gold Silk PLA from CC3D
