Mount

I mounted the swonvi using 3 of the incuded carriage screws and bolts along with

The bolts go inside of the chamber to the bottom. The Arcade 1up trackball top snaps on top over 3 of the carriage bolts. If I used 4 would have had 2 cut something. 3 is enough since I am also using 2 right angle metal thingies are used and screwed into plastic and cpo.
