I use TinkerCAD for 3D all the time. I thought I remembered and SVG button for laser cutting. So I did a quick test of 2 ft block with a radius on it. I then did a boolean subtraction of a cylinder. Then Exported it as a .SVG . It got wonky when it wasn’t centered. I wouldn’t try over 3ft in any direction. There used to be a big bug inTinkerCAD for anything over 9 inches in any direction.
