Summary

I printed the base with I think 10% infill, paused it at the top and filled it with dried sand to give it weight.

Print at 60% scale. The paddle rubber printed with TPU flex. Used super glue to join the halves, the rubber, and letters.

The paddles are removable, so you can play with them.

I attached the Solidworks file for the letters so you can change to something else.
