Based on c_taylor's lens cap, I've adjusted the outside diameter to fit a little more snuggly and added small retention bumps on four of the sides. I find that this version stays attached much better. Be sure to keep the tab rotated away from the main body of the Seestar. I printed using PETG at 250. No need for infil or supports since it's so thin.
