This is a trident I made as part of a Halloween costume. It prints really easily, and the hilt/handle threads into the main trident head nicely. They're separate parts, so you can easily print them in separate colors.

This prints really easily and quickly, flat on a printer bed for the head (I gave it a slightly flat edge so it sits nicely on the printer bed), and standing up for the handle.

You can also upsize or downsize it easily by scaling it in your slicer. You can even extend the length of the handle pretty easily by using the Cut command in your slicer to separate the thread from the rest of the handle and then vertically stretching the rest of the handle. For reference the size I printed it at is more of a cute Halloween prop.

Note that by virtue of being a trident it is somewhat pointy/sharp, but I did chamfer the edges slightly so as to not make it as sharp. But of course please still exercise approach caution when using, any injuries occurred are on you.
