I've been in the market for something like this for a while, something I can use for W12 and w20. The 30 taper piece should removable and the price is low. It does look physically larger than what I want, but maybe. hmmmm
 
@CWret's optical center (with light) is a bit further down that same thread linked above. I've seen his center. It's really nice!

He gave me a piece of acrylic rod to make my own, but I have not done it yet. Too many projects. My bad.

Step 1- a sharpe automatic punch on the layout intersection;
Step 2- then a small punch on an angle if some lateral adjustment is needed (like others described above); and

The little lights are designed for putting into party balloons before they are inflated.

Typical comments about these punches include:
1- by using proper techniques for center punching you don’t need one of these;
2- they don’t transmit enough light to see the cross hairs;
3- they are expensive;
4- they are even way more expensive if you can find one that has a light; and
5- not needed if you have a DRO.
