Using the foam that comes with the packaging of the Mighty Mouse, you can slightly alter it depending on the specifics of the Mighty Mouse used.

Needs 4-5 m3 screws to attach clips and hinge.

Clip tollerance depends on the printer used, some filing might be needed for the clips to clip in place.

I will print this and ship myself for 20 dollars including shipping, dm me on twitter: MightyAims
