Naca Duct - Thicker Base & 3 Sizes

This is a modified version of Jwmflying14's Naca Duct 44mm x 30mm x 10mm to have a thicker base because I found the original to be far too flimsy for use.

This version has a much thicker base which will better withstand knocks, say from putting in batteries etc...

Available in 3 sizes, original, larger & XL
