I can try on mine .. though it's limited to about a 2.5" cube .. (Original Micro 3d .. M3D: 3D Printers, 3D Printing Filaments, 3D Printer Parts - (https://store.printm3d.com/) )i really dig this concept!!
if you are going through the trouble of fabricating a special totem.... why not have someone 3d print a plate that lays on top of the sub...touching/filling the topography on top of the sub in key areas and creating a flat base on top
