This is a simple zone marker for positioning on a standard 25mm (~1") battle map. I've uploaded a 3x3 and 7x7, as well as the source SolidWorks file for making other sizes.

Hardly deserving of praise, but I like it.

Prints quite easily.

Simple to adjust if you have SolidWorks - you just need to adjust the linear pattern, add the additional bodies to the combine, then move the fillets to the correct edges.

If a particular size is needed, I'll be happy to add it.
