An automatic center punch is useful in the mechanical field. Usually, they are made of metal. Now I designed a 3D printable automatic center punch. It works very well. Also, I give you the easiest and effective upgrade method. Use a smartphone, the alignment to the punching center become very easy and visible. Hope it will help you a little. I bought a long spring. It is not necessary. If you use a shorter one the whole body can be decreased. I add the f3d file also. You can adjust the length according to your spring size.
