Did you bother to look into it at all? What you are asking doesn’t even make sense from a design standpoint.
Nobody asked for a car you can print.
The way they are building their electric truck is the smartest way. Using available, off-the-shelf parts that have proven reliability. Nobody is going to be using CAD to create custom parts. Reinventing the wheel is precisely the problem and Edison Motors is working to avoid those mistakes.
Also, they are taking design input/feedback at the consumer level right now, BEFORE they have a ‘completed’ product to purchase. This is as close to open source as you can get in my opinion.
You could literally buy the same parts out of a warehouse and build a logging truck yourself if you wanted to.
Or you can sit on the internet and complain without having any idea what you’re talking about.
