Hi everyone! I would like to receive some advices.

Hi everyone! I would like to receive some advices. I’m working on geodesic domes and i printed it without support. I think the result was quite good, but obviously some horizontal parts of the print was not. I tried to correct manually those parts with an hot bistoury, to fuse the pendant layers, merging it with the rest of the print. What do you think about this method?

Manually add support geometry to the model for the top 1/5th of the model. Or print in zero G.
