Animatronic mini Ear module

These are the ears from my animatronic mini head which fit onto the eye's I uploaded last year. The base plate has room for four servo's. The front two are for optional eye brows en the back two are for rotating. The up/down motion is made by servo's below the eye as can be seen in the video.

All the parts where printed in ABS and treated with an acetone vapour bath to make everything very smooth. After the vapour bath all holes were drilled to the correct size because the ABS would deform a little during the process. Please note that some parts require extra sanding to make all parts fit.

This is a list of all the hardware I used to made a pair of ears:
Please note some things can be made diffently and lenghts can vary in your design.
