Designed this trophy in Fusion 360 using simple geometry, coils, mirror, pattern, and loft tools. This was designed to hold a Golf Ball perfectly on top. Has a flat spot on the front where you can design an embossed placard, and hot glue it on, or just use masking tape and a sharpie (my choice).

Printing:

This should be capable of printing directly. There is one spot that can get a little loose in the accuracy, but it is hidden on the inside of the ball holder where it isn't noticeable.
