About overhang handling
See the diagram at the left. A standard Elna pattern disc has a small amountof overhang as shown by the arrow. Your 3d printer may or may not be able tohandle this.
If you select the option "Ignore", the generated model will include theoverhang unchanged, as shown here.
If you select the "Remove" option (the default), the overhangis removed completely. This is the simplest and safest approach.
The "75°" option keeps the overhang but slopes up at a 75° angle, making iteasier for printers to handle.
The "60°" option slopes up at a 60° angle, making iteven easier for printers to handle, but producing a weaker disc.
