Or both. Pointy_external_indicator = false; // Number of facets of rounding cylinder ct = -0.1; // circle translate? Not sure. Pad = 0.2; // Padding to maintain manifold rotate_extrude(convexity = 5, $fn = top_rounding_faces square(top_rounding_radius + pad, top_rounding_radius + pad); rotate_extrude(convexity = 5, $fn = stem_faces); // Widening part at the top if you want. Putting everything together is a consideration. FDM printing is the two.
