Using SCAD primitives to create fillets

thingiverse

The primitives offered by the SCAD language, specifically the minkowski() operation, can be employed to automatically add fillets to every concave seam of an object. Nevertheless, this operation is costly and likely not a practical approach to tackle issues. This scad file demonstrates a shape comprised of three interlocking cuboids and a cylinder with fillets created using a very polygonal sphere. A higher-resolution sphere would yield significantly better results, yet on my aged MacBook it would take numerous hours or more to process.
