Funola's over-the-tube design does the same thing.

In my case, as in Mike's, I use a small-diameter hard plastic tubing that goes down the dipstick tube to the bottom. Either way works.

My first attempt at a top sider on the Mercedes used a 1/4 o.d. tube inserted into the dipstick tube. It worked fine to remove the oil but was slow. My next design clamped a hose over the dipstick tube. Worked equally well to remove the oil except much faster.
