JP6 Case Repair

[DR5Guy]

My JP6 case has two cracks. Is there any non-destructive way to remove the Styrofoam liners so I can repair it from the inside?

Thanks

Is this one of the ABS plastic cases, or a wooden shell case?

Generally the cases are glued and/or stapled together. Not easy to take apart or repair.
