Oil funnel (threaded), for European jugs

A vented threaded funnel for a European oil jug. Measure the outer diameter of the threads on the jug, you should get either 45 mm (DIN 45 thread, also called KS 45) or 50 mm (DIN 50 thread, also called KS 50). The wall thickness of the funnel is typically 2.5 mm.

Includes CAD so you can easily modify it to other threads. Or you can comment and I will make a version with a different thread.

Edit: A very slight change in the tolerances for the threads, which should make more prints fit more jugs. I am also making a cover and a stand for the funnels.
