3D PRINTING SETTINGS TopGrind, MidCase & BowlAdapt2 = Shells x3 (1.2mm) Top/bottom x5 layers - 16%infill For the Base.stl go with 2xshells on 100% infill (not something I'd ever recommend) LargeParticlePlate needs to be 3xshells & 100% for durability. TO FINISH: MidCase might need sanding very slightly (don't over do it) on the inner surfaces to ensure a smooth turn, Lube top grinder with hemp oil for even easier shredding!
