Here is my submission to the MakingMerry holiday ornament contest. Going into this contest, I wanted to create a simple holiday ornament that integrated a light source in some way. I began breaking out my breadboard and came up with a basic circuit, but it required 2 AAA or 2 AA batteries. I started to realize how heavy the model would get with two batteries configured inside of the print, so I started thinking again. I realized that lights on the tree would be a simple yet effective way of creating a nice light source without soldering or having external batteries. I started to think about how I could really include a bunch of stuff into one ornament and came up with this great idea of having an interchangeable top, so different days you could have different colors or different designs. I own a Printrbot Simple but wanted a two color ornament so the interchangeable top idea really started to justify itself in my head so I then started to design in Solidworks. The two tops feature my version of the Makey, which includes a Santa hat and two presents, because this season is all about giving. The next top is a holiday tree. I hope you enjoy my submission and have as much fun viewing this and printing it as it was for me to design it and print it myself! https://www.youtube.com/watch?v=UWELlLG7BCMPlease use your host software to print these models upright. The Tree and Makey should be standing up, and the base circle should be flat.
