That 3d printable push-pull spinner model looks promising.
If printing one of those is not an option, there are only a few games that use a push/pull style spinner: Discs of Tron, Forgotten Worlds, Kozmik Kroozr, and Zwackery.
Discs of Tron and Zwackery have an 8-way triggerstick with thumb button and a push-pull spinner. (stick + spinner + 4 buttons)
- The rocking foot pedal mentioned in the thread that Vocalitus linked is an easy substitute for the push-pull spinner in these games.
Forgotten Worlds has an 8-way stick and push-only spinner. (stick + spinner + 1 button)
- You can use an 8-way triggerstick and regular spinner for this game.
Kozmik Kroozr has an analog triggerstick and push-only spinner. (analog stick + spinner + 2 buttons)
- You can use an analog (or 8-way if you don't mind the loss of fine controls) triggerstick with thumb button and regular spinner for this game.

EDIT: Eco Fighters uses a push-only spinner like Forgotten Worlds. (Option added in MAME 0.169.)
