40 mm Fan Cover Guard

pinshape

This is a unique 40 mm fan cover designed specifically for my Prusa i3 printer's J-Head duct. I required it to safeguard that fan and provide space for warning stickers. When attached with 3 mm cap screws, they will recess into the design, preventing them from sticking out on top. It offers protection for fans placed atop objects. The cover's unique design prevents small items from slipping through openings found in standard fan guards.
