Here is a customizable version of a Chanukah dreidel (top toy). I made these for my nieces and nephews for Chanukah. Unfortunately, two of my nieces had names longer than 4 letters, so I created a non-traditional 6-sided dreidel.'
Using Blender, I customized each side to spell-out names.
Open the Blender file and edit it. Add text to write whatever you want. Convert the text to a mesh, and "extrude" it to create a 3D object. Export the various parts (except the stem) to an STL file and print it.
Separately, print the stem STL and insert it into the dreidel. You may need to drill or file a little to make it fit. You may want to use a little super glue as well.
Go for a spin!
