Sanjay Mortimer E3D Founder Commemorative Hex Tile -- Split into a border and main piece.

I took Pooch's great original file and split the border to a separate piece so that the border can be printed in a single color without a multi-material print.

There is no clearance between the two parts and this creates a good friction fit on my printer. If needed, you can scale the border up or down for a better fit.

The .3mf file contains both parts. One will need to turned off to only print the other.
