Baby Yoda/Grogu Echo Dot 3 Base

Echo Dot 3 stand with Baby Yoda/Grogu ears

This will need some support to hold up those big ears.

I've also had reports of "buzzing" while playing music. I haven't experienced this myself, but you may want to experiment with scale: either a few 10ths of a percent smaller or larger to adjust the fit.
