Quilt Square Templates 4 to 8 and 4 to 10 inches

My wife asked for a 3d printed quilt square template that was more precise and durable than the several cardboard squares she had been using. The outer edge is 10 inches and each outside square edge is one inch smaller down to 4. The empty spaces are 3mm to easily accomodate her rolling cutting tool (looks like a pizza cutter). I don't know much about quilting but hope this helps someone else too.

Aside from quilting, it might make a nice coaster (scaled down) or plinking target?
