One idea could be getting your dad a high-quality model kit to build. You could find out if there are any specific models he has been interested in or if there are any new releases he hasn't picked up yet. Another idea could be getting him some quality model building tools or materials, such as glue, sandpaper, and paints. If your dad also likes to display his completed models, consider getting him a display case or shelf to showcase his collection. Lastly, if you wanted to go a more unique route, you could consider finding a local model building class or event that he could attend as a gift experience.
Or you can get him a star map with the date when he was born.
