Thanks for the link. I've just used a piece of chalk with one of the edges as the reference. This looks much more professional and might be more accurate. I might have to get one myself.
SO Exciting!!!
This one's a much better price ($4.73) and also includes with free shipping:

Mine arrived from China less than a week after ordering, and it's not only beautiful, flawlessly clear acrylic, but it's dead-on accurate with regard to an extremely perfect fit against the standard 2 1/4 cue ball. Not a whisker of a gap.

I have the one Arnaldo posted and love it. I use it at home all the time for the wwyd threads. If I see a situation I want to mark to practice, I slide this under the balls, and then put a doughnut in the center of the half circle of the clear plastic. It might seem like overkill, but it’s way, way, way, easier to mark the balls this way then simply picking them up and sticking a doughnut underneath.
where to purchase this?Best ball marker I know of is from Gibbi Tkatch. It’s small butt has weight. There’s an indent where you can use a finger to hold it down while you place or remove the ball.
It’s what you see being used at CSI events.

It would be better if one of the dimensions was 57.15/2 = 28.58 mm. The ball marker the snooker refs use has a half-ball width.Bob, I just measured mine with inch dial calipers. None of the dimensions are are close to any inch fraction. Then I switched to my metric dial calipers. The part was designed in mm. The dimensions are 80 mm x 40 mm x 12 mm. All 3 dims are pretty much on the nose (plus 0/minus .05 to .10 mm).

As I mentioned before, there are times when you want to mark the position of the ball. Also, sometimes people want the ball placed exactly on a spot. In that case the use is the second half of returning a ball to its previous spot.Wow, I never saw until this video all of the uses. Bob, is this what you meant? And for American Pool, is the only use-case: ball cleaning (not ball marking, thus you can leave the tool on the table), and measuring if a ball fits on the spot?
I checked my clear one from ebay. It appears to me to be machined and polished, rather than injection molded. If there is a lot of interest for a specific design, I can draw one up, and have them CNC machined. I'd guesstimate the cost would be in the $20 range per. (this is my day job).
