Here are the bunny ears that these insets go into: https://www.thingiverse.com/thing:3897846
Remixed for an easier print and fit in the bunny ears. Also matches the curvature of the head. Flat side facing out when placing them onto ears.
Tip: When printing the ears use the “fuzzy skin” setting in Prusa Slicer.
