When first opened, the initial presentation is a card to make you feel good about the purchase. Generally good content, but the heart diagram is a bit cheesy.
Underneath the card there is ample bubble wrap protecting the purchase. The card gives a nice touch so it feels like more than just a part shoved in a box. It is a totally different display compared to if the bubble wrap is the first thing seen.
This photo shows the texture from a 3D printed aluminum. The website has plenty of documentation to describe the strength and look of their different materials.
Here is the part in place in the music box.The raised feature on the hinge side is what holds the shaft in place. Once it was in place I added some oil that would be for a model train for good measure. Finally, I could reap my reward and hear the song.
