I designed this stand as a 4 piece unit so that it can to be fitted together as needed and taken apart to pack for travel. It assembles snuggly by pressing the parts together, if printed with ABS. Disassembled, it lays flat for easy packing. I added small bits of grippy rubber where the PX3 lays on the stand and added grippy rubber feet to the bottom for stability. It works very well for my application.
