Print one of each item separately, then assemble all parts together. Each component can be snap fitted except for the arms which will require gluing or a dab of acetone. I printed it using the following settings: Battery pack back ball and frontball with battery door: orange PLA at 0.2mm layer height, 10% infill, 2 shells. The frontball was printed with support, while the rest were done without. Arms: Gray or silver ABS at 0.2mm layer height, 10% infill, 2 shells with support. Nubbin: Silver PLA at 0.1mm layer height, 15% infill, 2 shells, no support. The red part of nubbin was printed with red PLA at 0.1mm layer height, 15% infill, 2 shells, no support but may benefit from a raft to prevent damage during removal. Partition clips: White PLA at 0.2mm layer height, 10% infill, 2 shells with support. Centre crystal: Translucent blue at 0.2mm layer height, 10% infill, 2 shells with support. For the LEDs, I bought a string of 10 LEDs on a battery pack; five would have been better. The wiring and connectors from the battery pack were removed and placed into the battery pack back ball. To assemble: Push the red part of nubbin into the nubbin for a tight fit that won't require gluing. Next, push the nubbin into the frontball for another very tight fit that may need some persuasion. The surface of the nubbin meeting the curved face of the frontball has been designed to match, so you might need to rotate it slightly for a flush fit. Insert the centre crystal into the front ball using its flat sides for assistance; minimal force should be required. Push one partition clip into the front ball with clips sticking out, then insert your LEDs and add the other partition clip, ensuring LED wires pass through the middle gap. Verify that the printed battery pack has been wired up with the on/off switch exposed and bunch excess wiring in the provided space. There's a thin guide for LED wires to follow above the batteries into the front part. Snap the front and back together; they should fit tightly. Use Acetone or glue to secure the arms.
