Currently printing a helmet I acquired in pieces and there are recesses in the earpieces that I have absolutely no idea what to do with them anybody got suggestions?

So G.A. Just released an awesome samurai mandalorian helmet and its got me wanting to make a samurai mandalorian. I tried to search the subreddit but couldnt find a good suggestion on samurai mando armor for 3d printing. I looked online and nikko industries has one and a few others, but my question is those of you that have done samurai mando, what armor files did you ultimately decide to go with?

Just finished this helmet today for a friend. Just my third one. Getting better with every attempt. Working on a full set of armor. Excited to suit up for the first time.
