This is V2 from thing: https://www.thingiverse.com/thing:2773933
I really liked how much squash balls did take vibrations and noise off from my MK3 ( https://www.thingiverse.com/thing:2823821 ), so here is my try for low profile ball mount for MK2 platform.
AA - Battery for size comparsion.
I printed without supports, but these do need supports.
I used 8x 160*2.6mm zipties for mounting.
Use pliers to pull zipties very tight!
Plans for v2.1: make a bit bigger holes for zipties & check details (ETA: unknown, really busy at work)
Let me know how this thing works for you?
You may play with your settings.
