Re: E28 powerhouse generator parts
Optima batteries are sealed but have a pressure release valve that will pop off to release excessive pressure due to over charging. Under normal conditions the hydrogen gas will recombine with the acid. For a 6 volt battery they recommend not exceeding 7.5 volts and for a 12 volt battery, 15 volts. A volt meter in addition to the ammeter will provide better monitoring of your battery charging.
To make a new part I would tend to go with phenolic sheet or Delrin. Or, if 3D printing is available then go with that with the material recommended by the printer. If the original drawings are available, then use them for the 3D model, as Brent recommended. But if not available then use the best guess from measurements of the original part.
