I designed this for my boat, but it may be useful for any motor with a petcock drain. My boat antifreeze drain is obstructed by some cables, which doesn't allow use or a normal funnel to collect the drained antifreeze. The rectangular portion of the funnel slides over the petcock wingnut. The lower cylinder is 1/2" OD to accept a hose which can then go to a collection bottle. I made this out of polyurethan so it would be flexible enough to install of the petcock wingnut.
How I Designed This
I created a hollow box, then created a hollow cylinder and placed them about 30mm apart. Then I used the Create-Loft function in Autodesk Fusion to join the two shapes.
