Is there an electric choke conversion for a six pack setup???

This evenings bench test was successful. Using a 30watt 3d printer heater, Test supply voltage was 14.00 volts, modulated down to 8.00 volts through the DC module. The heater runs at .8 amps at 237 degrees. Fully open choke in @ 6min. Now it needs to be made into some sort of package.
