Wanted to center drill some wood dowel. Had no way to center other than another center marker i made on my printer. It's nice but just want cut the beef. It has a off set depends on how thick or sharp pointed your pencil or marker is. That's just no good. I also printed the patented center maker i found here on thingiveres and it was bad. It would had been great if it could had been extra fine machined. It was just sloppy and not near noon of it was from my printer.

So i had a prayer meeting, some deep thinking and came up with this. It is designed for using a fine lead mechanical pencil i have had for years. Works great and now i will share it with ya'll.

Small will mark up to 1.5 inches diameter. Large will mark up to 6 inch diameter stock.

Quick way to go, no moving parts, prints fast and will last forever.

Hope you enjoy. Happy Printing!!
