Threaded Oil Funnel

Sturdy threaded oil funnel originally designed for a 7.3 Powerstroke motor, but should fit other Ford vehicles (and possibly other makes too).

Threads are roughly M32x3.5; major diameter of the printed threads is ~31.4mm.

Print it big end down with concentric contours up to the radius where the wall thickness starts to change.

Fusion 360 and Iges files are included.
