These are simple alphabet buttons.
Fun for everybody, definetely a win with kids.
In order not to interfere with the letters, These are installed through a sigle hole in the back.
Print these with the letters facing down.

I recommend printing a few of these at a time to give time for the layers to cool on the back lug, where the hole is located.
Scale these to the size you need.
