Star Pendant

I purchased the Adafruit Space Invader pendant but I didn't want to simply hang a PCB on my neck, so I created this instead. You can follow the project on Adafruit's website for detailed instructions on the electronics. Just print this case off and assemble it. This project is beginner-friendly. Print the battery holder with supports in place. Print everything else without supports but you may need either a brim or printing disks at the pointy parts due to sharp corners, which might pull up off your bed if it's not heated properly. The top and bottom snap together but you'll require a couple of small screws and nuts for the battery holder. Optionally, change out the JST connectors for something more logical. I made mine without a switch and programmed it to loop indefinitely instead. To disassemble it, simply squeeze the bottom part and pry it apart. Program your Gemma before assembling everything together and you'll never have to take it apart (assuming you've used alternative JSTs) unless you tire of the animations. To ensure proper orientation, mount it so that what would normally be the necklace part if you were simply hanging the PCB is pointing towards the small necklace holes, or away from the large battery hole. The large battery hole should go at the bottom. There's enough room inside for some wiggle room in case you don't get the wire lengths quite right. You might need to stick one piece of wire underneath the opposite side of the backpack so that it sits evenly (you'll understand when you do it). The circuit board assembly will move around slightly, especially if you push it in too far. This can be stopped by taping it or placing something non-conductive behind it, or simply readjusting as necessary.
