3D Print - First Pendant Prototype

Today I am going to show you the result of my first prototype 3D printed. I used PLA filament and it took less than 40 minutes to print the base and the cap of the pendant. The pendant is 40mm wide and 12mm thick. Here's what it looks like:

It snaps somewhat okay, but I am not really satisfied. I will 3D print a newer version once I get my parts working. I will use this just for testing and planning a better model. I need to find a way where I can make the three parts clickable. One way is to make a circle with 3 holes that would hold the push buttons in place inside the case. Also for testing purposes, I will reprint the base with an open bottom area where I can connect the cables and components to a breadboard and Arduino board. In the newer version, I will also add a bail to the pendant so the user can insert a chain and hang it over their neck.
