Exo Skeleton Spine Threaded Base

Simple modification to add threads to the inside of the spine connector. This allows transparent plugs to screw right into the base.

Files include the modified spine base, a sample plug, and the thread as a single object, to allow for custom designs. The premade plug's orientation ensures that any logo you add to the top sits upright. Idea behind this is to add LEDs inside the spine, add your favorite evil corpo logo to the plug, then print the latter with transparent filament.
