Helps to reduce mechanical noise transference from Creative Pebble (V3) USB Speakers, and fits nicely into the elliptical footing enough to hold itself in place when you (gently) move the speakers.
Printed with Polymaker 95a TPU
Works best if you create a middle section with 0 perimeters. The lack of solid walls, and I believe the difference in material density (from being infill only) helps to reduce (but not eliminate) mechanical transfer from the speaker body to your desktop. I included a .3mf file with my part modifiers.
I printed with a 0.6mm nozzle, 5% infill and 3d honeycomb infill pattern as this created the least sealed pockets this pattern alternates directions every-other layer preventing the creation (again mostly) of any solid walls that would directly transfer energy or air pockets that would increase the rigidity of the part.
