This model is a simple, lightweight and robust centre finder with line increments of 2.5mm on either side. It doesn't require any other parts and so is simple to assemble and use. If the 3D printed bolts don't fit, reprint at 97% scale or sand down. I hope you enjoy it and please give any feedback so I can improve my modelling skills.

Throughout the many models I will release, I will keep them simple and easy to print, and I am aiming at creating 3D tools and accessories that don't require any additional parts. So I you would like to support me, please check out my other tools and accessories I have made for you and me.
