So this is just a remix of ababemilo's excellent Cylinder Center Finder. However, my minor twist was putting a name on it.
“Why” you ask? Well, so my family members don't throw it out in the trash not knowing what it is. If you're anything like me, your family constantly takes tools of off your meticulously organized tool bench and never returns them only for you to find said tool days, weeks or months later laying in the garage under the gardening supplies. That's if you ever find them at all.
So, hopefully, having a name on this someone will question it before launching it into the trash because they don't know what it is. :)
This needs no supports if you print it face down.
