A Porsche driver who decided he had a Subaru for your time. He left the car for a few days. Clearly damaged his underbody, including exhaust. Still though. Looks good in WRX clothing.

Question: I need to design a simple pill shaped 14"x 4"x 1/8" object to send to a local thermoform 3d printing company. What software do I need? I haven’tbeen able to figure out gravit designer or blender. I know this is probably really easy for people with 3d graphic design backgrounds, but I am overwhelmed.
