Not an answer to your question asked but an option so that you don’t need to ask the question in the future...
form-a-funnels are the cats meow when it comes to getting the filter off without making a mess. Nothing really worked until I tried it.

Hope this helps.
I know it's a little thread drift but since it's already sidetracked- I saw an oil filter drain tool on Acft Spruce, anybody ever used this one?

Yup. If your filter is horizontal like mine is, it only drains about half way.Of course this assumes that the filter is at an angle so that it will drain.
Why? Phillips screwdriver and a small hammer accomplishes the same thing, and they are already in my toolbox. Give it a couple hours and you'll remove the filter without any drips.
I have found that simply using an old margarine container to place under the filter while draining the filter works great.
When I use the oil container, I find it easy to just crack the oil filter loose, put a good size rag under the filter to catch any drips, position the oil container underneath the filter with one hand and remove the filter with the other.
I've been using windex for the belly for quite a while. Recently I started adding about two tablespoons of Nuvite S to the bottle and shaking until it dissolves. That cleans the oil off and gives a light polish to the surface as it's wiped down.Will Dawn dishwashing liquid harm unpainted airframe? thinking about using it to clean the oil off the belly, followed by a good water rinse.

Great idea and a business opportunity for someone to create a re-usable fitting that could punch and thread into hole in the filter. Attach the hose and walk away for a few minutes...Folks, a fellow mechanic shared with me the easiest way to deal with the oil filter, if you have compressed air available.
1. punch hole near the back of the can on the upside.
2. Attach air blow tool to air hose (kind with rubber tip)
3. Adjust air pressure relatively low, say 40 psi
4. Hold rubber tip to hole you punched and apply air pressure
5. continue blowing air through the filter for approx 5 min
This will leave inside of filter dry, driving all oil back to crankcase, and has filter ready to cut after removal, with no mess.
Method works best with warm to hot oil.
Usual precautions about pressurized air...eye protection, hold nozzle tight to hole in filter, etc. First time I tried, could not believe how easy and effective this method is...especially for folks that can't wait over night for draining.
Couple issues I can think of that would absolutely steer me away from this:1. I've been thinking of using my pressure washed to clean the engine and accessories. Any known reason this shouldn't work on a completely cold engine? I realize I'll need to dial back the pressure some.
Nothing trapped in the filter media follows that oil backwards into the engine, eh?]
The oil system pushes oil through the filter at 50-90 psi. You can adjust your compressed air to a pressure you are comfortable with. I would say the oil is most likely to return to the engine via the same path it does when the engine is operating, and thus is unlikely to dislodge anything from the filter.
However, even if it flows in reverse direction, if you are using less pressure than what drives the oil through normally, it is unlikely to dislodge.
Alternative is to use a non-Lycoming filter adapter that holds the filter near vertical so oil drains back naturally.

Could you punch a drain hole AND a vent hole so the check valve is not in play? Just don't put it on the line your filter cutter will slice, probably below.
