If you have trouble printing, increase the z-hop to 0.8 and lower the extrusion multiplier to 0.90, since the shape of the pieces causes the tips to contract when the circles are printed and the nozzle collides with the piece, breaking it.
You can glue the two parts but it is not necessary, turning the inner piece creates different decorative motifs.
