Unit coherency ring (3 inch ) for tabletop miniature games

Starcraft TMG is coming. Someone on discord says It needs a unit coherency tool of 3 inches. I give it a try and here is the end result. This is for 32mm base, 3 inch coherency circle. I make 4 quarters of a whole ring so that you can use it when your leading model is in a tight fit area. There is also a whole ring in the file. I use petg. It looks very thin but it's actually quite durable than I thought.
