Welp... Since we know essentially NOTHING about your skill level I might as well just throw CAD Modelling paired with 3D Printing into the Room 🤨

Buy a 1:35 sized Kit for reference, Dust off the Calipers, prepare an Excel with a 1:35 > 1:16 Conversion Formula and prepare a large bucket of C8H10N4O2? 🤔
